Conformational transitions of this protein are believed to contribute to disease etiology, but the conformations that drive pathology remain unclear. To address this question, we screened an exhaustive library of alpha-synuclein missense variants for their toxicity in yeast, a well-validated cellular model for alpha-synuclein pathobiology. By examining the pattern of mutations that disrupts cellular toxicity, we were able to build a model for the structure of the toxic species.",
        "method_text": "A double-stranded DNA library based on human alpha-synuclein cDNA was produced by commercial oligonucleotide synthesis and assembly. The designed library encodes all single missense variants of alpha-synuclein, each encoded by a single codon. This library was cloned in frame with a C-terminal GFP fusion, and 26bp random barcodes were appended 3’ to the stop codon to facilitate repeated selection. This construct was cloned under control of an inducible promoter and transformed into E. coli. Following restrictive transformation, the final library diversity was ~60,000 unique clones, corresponding to ~20 barcodes per missense variant. The barcoded coding region was amplified and analyzed by long-read MiSeq in order to associate barcodes with coding sequences. The resulting lookup table expedites subsequent quantification of variant frequencies.\r\nThis plasmid library was then transformed into yeast. Selection was performed by inducing expression and collecting aliquots over time. Additional experiments were performed in yeast treated with small molecules. Finally, the expression level of each variant was estimated by cell sorting yeast cells based on the fluorescence of the GFP fusion.",

Each codon for amino acid positions 488-516 of the human TpoR protein, encompassing the TM and partial JM regions, was independently randomised using degenerate (NNN) primers (IDT) to encode all 64 possible codons. Plasmid preparations for all positions (488-516) were pooled together in equal amounts to obtain a library containing all 1,856 possible DNA variants. The frequencies of variants in each library were determined by Illumina sequencing, which confirmed 100% representation across the randomised region and constitutes the unselected control sample.\r\n\r\nThe library was transfected into HEK293T cells along with retroviral packaging vectors using calcium phosphate transfection. After 48 hrs, supernatants containing virus were harvested and sterile filtered for transduction into Ba/F3 cells.  The pooled retroviral library was used to transduce 10^6 Ba/F3 cells at a multiplicity of infection ~0.1, generating ~10^5 transductants for each of six biological replicates. These six cultures were treated with 5 μg/ml puromycin (on IL-3) for 48 hours to yield pure virus-positive cells. Cells for each replicate were split in half and cultured in the continued presence of IL-3, or were washed to remove IL-3, and subjected to another 48 hours culture. mRNA was prepared from the live cells that remained at the end of this procedure.\r\n\r\ncDNA was prepared from 1 μg of total RNA using the TpoR-specific reverse transcription primer containing a 16 bp unique molecular identifier (UMI) and an Illumina adapter. cDNA was amplified to add illumina adapters and indexes for sequencing using an Illumina NextSeq kit with 140 cycles in the forward direction and 160 cycles in the reverse direction.\r\n\r\nThe paired-end reads from Illumina sequencing runs were separated into samples based on Illumina index sequences using Cutadapt v1.157. De-duplication based on the UMI was performed using UMI Tools v1.15 after sample separation. Reads were trimmed to the region of interest and filtered for length using Cutadapt prior to analysis with Enrich2 v1.2.0. \r\n\r\nTo determine mutations that confer constitutive activity log ratio enrichment scores were calculated for each of the six replicates by comparing the variant counts in the unselected plasmid library with those remaining in Ba/F3 cells after 2 days of culture in growth factor free media using “wild-type” (all synonymous DNA sequences encoding the WT amino acid sequence) count normalisation. To determine mutations that confer increased activity on the S505N background six replicates of library-containing BaF3 cells grown in IL-3 were compared to six replicates of library-containing BaF3 cells grown without growth factors.

High-throughput DNA sequencing was used to measure the frequency of each variant. Six time points (including the starting time point) were measured during the course of the assay. Three replicate assays were performed.",

        "abstract_text": "Insoluble protein aggregates are the hallmarks of many neurodegenerative diseases. For example, aggregates of TDP-43 occur in nearly all cases of amyotrophic lateral sclerosis (ALS). However, whether aggregates cause cellular toxicity is still not clear, even in simpler cellular systems. We reasoned that deep mutagenesis might be a powerful approach to disentangle the relationship between aggregation and toxicity. We generated >50,000 mutations in the prion-like domain (PRD) of TDP-43 and quantified their toxicity in yeast cells. Surprisingly, mutations that increase hydrophobicity and aggregation strongly decrease toxicity. In contrast, toxic variants promote the formation of dynamic liquid-like condensates. Mutations have their strongest effects in a hotspot that genetic interactions reveal to be structured in vivo, illustrating how mutagenesis can probe the in vivo structures of unstructured proteins. Our results show that aggregation of TDP-43 is not harmful but protects cells, most likely by titrating the protein away from a toxic liquid-like phase.",

Here, we developed a deep mutational scanning framework that produces exhaustive maps for human missense variants by combining random codon mutagenesis and multiplexed functional variation assays with computational imputation and refinement. We applied this framework to four proteins corresponding to six human genes: UBE2I (encoding SUMO E2 conjugase), SUMO1 (small ubiquitin-like modifier), TPK1 (thiamin pyrophosphokinase), and CALM1/2/3 (three genes encoding the protein calmodulin). The resulting maps recapitulate known protein features and confidently identify pathogenic variation. Assays potentially amenable to deep mutational scanning are already available for 57% of human disease genes, suggesting that DMS could ultimately map functional variation for all human disease genes.",

The tested sequence is expressed in between a chimera of ToxR dimerization-dependent transcriptional activator of a chloramphenicol-resistance gene and $\\beta$-lactamase. In this construct, the membrane integration of target sequence determines the bacterial resistance to ampicillin and the self-association correlates with the chloramphenicol resistance.

The mutagenized HA-BRCA1 fragments were then ligated into a modified version of vector pcDNA5/FRT-TO at the BRCA1 cDNA EcoRI and HindIII sites. Barcodes, in the form of 16-base oligonucleotides, were then inserted at another multiple cloning site. \r\n\r\nThe libraries were transfected into HeLa-DR-FRT cells. HeLa-DR-FRT cells were derived from HeLa-DR cells described in Ransburgh et al. 2010 and have integrated a flippase recognition target (FRT) sequence from the pFRT/lacZeo plasmid (Thermo Fisher Scientific) as a landing pad. HeLa-DR-FRT cells are a reporter cell line such that it contains two inactive GFP-encoding alleles in its genome. Transfection and expression of an I-Scel endonuclease would induce a double-stranded DNA break in a site-specific manner at one of the inactive GFP alleles. Homology-directed repair (HDR), if functional, would use the other inactive GFP allele as template to correct and activate the broken GFP allele. Thus, if HDR is successful, the cell convert from GFP-negative to GFP-positive.\r\n\r\nCells transfected with the BRCA1 libraries were treated with siRNA against endogenous BRCA1 and pCBASceI to induce double-stranded breaks as described above. Then, the cells were sorted using FACS and genomic DNA was collected. Barcodes and sample indices were sequenced using a Nextseq 500 High Output 75 base kit.",

To address this question, we screened an exhaustive library of alpha-synuclein missense variants for their toxicity in yeast, a well-validated cellular model for alpha-synuclein pathobiology. By examining the pattern of mutations that disrupts cellular toxicity, we were able to build a model for the structure of the toxic species.",

The designed library encodes all single missense variants of alpha-synuclein, each encoded by a single codon. This library was cloned in frame with a C-terminal GFP fusion, and 26bp random barcodes were appended 3’ to the stop codon to facilitate repeated selection. This construct was cloned under control of an inducible promoter and transformed into E. coli. Following restrictive transformation, the final library diversity was ~60,000 unique clones, corresponding to ~20 barcodes per missense variant. The barcoded coding region was amplified and analyzed by long-read MiSeq in order to associate barcodes with coding sequences. The resulting lookup table expedites subsequent quantification of variant frequencies.\r\n\r\nThis plasmid library was then transformed into yeast. Selection was performed by inducing expression and collecting aliquots over time. Additional experiments were performed in yeast treated with small molecules.

        "abstract_text": "Deep mutational scanning (DMS) enables data-driven models of protein structure and function. Here, we adapted Saturated Programmable Insertion Engineering (SPINE) as a programmable DMS technique. We validate SPINE with a reference single mutant dataset in the PSD95 PDZ3 domain and then characterize most pairwise double mutants to study epistasis. We observe wide-spread proximal negative epistasis, which we attribute to mutations affecting thermodynamic stability, and strong long-range positive epistasis, which is enriched in an evolutionarily conserved and function-defining network of ‘sector’ and clade-specifying residues. Conditional neutrality of mutations in clade-specifying residues compensates for deleterious mutations in sector positions. This suggests that epistatic interactions between these position pairs facilitated the evolutionary expansion and specialization of PDZ domains. We propose that SPINE provides easy experimental access to reveal epistasis signatures in proteins that will improve our understanding of the structural basis for protein function and adaptation.",

Here we experimentally measure how all amino-acid mutations to the RBD affect expression of folded protein and its affinity for ACE2. Most mutations are deleterious for RBD expression and ACE2 binding, and we identify constrained regions on the RBD's surface that may be desirable targets for vaccines and antibody-based therapeutics. But a substantial number of mutations are well tolerated or even enhance ACE2 binding, including at ACE2 interface residues that vary across SARS-related coronaviruses. However, we find no evidence that these ACE2-affinity enhancing mutations have been selected in current SARS-CoV-2 pandemic isolates. We present an interactive visualization and open analysis pipeline to facilitate use of our dataset for vaccine design and functional annotation of mutations observed during viral surveillance.

We also provide decomposed single-mutant scores, which are the primary mutation scores we use in our analysis of the data. In each of these datasets, the binding score is a delta-log<sub>10</sub>(_K_<sub>D,app</sub>) metric from the variant titration curves, and the expression score is a delta-log(mean fluorescence intensity) measurement of cell surface expression. Both metrics are relative to the unmutated SARS-CoV-2 reference sequence phenotype, polarized such that a positive value indicates higher affinity or expression compared to unmutated SARS-CoV-2, and a negative value indicates decreased affinity or expression compared to unmutated SARS-CoV-2.\r\n\r\nSee the [preprint](https://www.biorxiv.org/content/10.1101/2020.06.17.157982v1) or [GitHub repository](https://github.com/jbloomlab/SARS-CoV-2-RBD_DMS) for additional information.",

Here, we developed a deep mutational scanning framework that produces exhaustive maps for human missense variants by combining random codon mutagenesis and multiplexed functional variation assays with computational imputation and refinement. We applied this framework to four proteins corresponding to six human genes: UBE2I (encoding SUMO E2 conjugase), SUMO1 (small ubiquitin-like modifier), TPK1 (thiamin pyrophosphokinase), and CALM1/2/3 (three genes encoding the protein calmodulin). The resulting maps recapitulate known protein features and confidently identify pathogenic variation. Assays potentially amenable to deep mutational scanning are already available for 57% of human disease genes, suggesting that DMS could ultimately map functional variation for all human disease genes.",

To address this question, we screened an exhaustive library of alpha-synuclein missense variants for their toxicity in yeast, a well-validated cellular model for alpha-synuclein pathobiology. By examining the pattern of mutations that disrupts cellular toxicity, we were able to build a model for the structure of the toxic species.",

The designed library encodes all single missense variants of alpha-synuclein, each encoded by a single codon. This library was cloned in frame with a C-terminal GFP fusion, and 26bp random barcodes were appended 3’ to the stop codon to facilitate repeated selection. This construct was cloned under control of an inducible promoter and transformed into E. coli. Following restrictive transformation, the final library diversity was ~60,000 unique clones, corresponding to ~20 barcodes per missense variant. The barcoded coding region was amplified and analyzed by long-read MiSeq in order to associate barcodes with coding sequences. The resulting lookup table expedites subsequent quantification of variant frequencies.\r\nThis plasmid library was then transformed into yeast. Selection was performed by inducing expression and collecting aliquots over time. Additional experiments were performed in yeast treated with small molecules. Finally, the expression level of each variant was estimated by cell sorting yeast cells based on the fluorescence of the GFP fusion.",

        "abstract_text": "The receptor binding domain (RBD) of the SARS-CoV-2 spike glycoprotein mediates viral attachment to ACE2 receptor, and is a major determinant of host range and a dominant target of neutralizing antibodies. Here we experimentally measure how all amino-acid mutations to the RBD affect expression of folded protein and its affinity for ACE2. Most mutations are deleterious for RBD expression and ACE2 binding, and we identify constrained regions on the RBD's surface that may be desirable targets for vaccines and antibody-based therapeutics. But a substantial number of mutations are well tolerated or even enhance ACE2 binding, including at ACE2 interface residues that vary across SARS-related coronaviruses. However, we find no evidence that these ACE2-affinity enhancing mutations have been selected in current SARS-CoV-2 pandemic isolates. We present an interactive visualization and open analysis pipeline to facilitate use of our dataset for vaccine design and functional annotation of mutations observed during viral surveillance. See the [preprint](https://www.biorxiv.org/content/10.1101/2020.06.17.157982v1) for more information.",
        "method_text": "We constructed duplicate libraries of mutant variants of the SARS-CoV-2 receptor binding domain (RBD), and cloned the library into a yeast surface-display platform. We used FACS-seq assays to determine variant expression and binding scores: 1) We labeled RBD variants for cell surface expression levels (a correlate of folding stability), and/or binding of soluble ACE2 ligand across a range of ACE2 concentrations. 2) We used FACS to partition our library into bins of expression or binding. 3) We sequenced the variants from within each bin. 4) From the distribution of sequence reads across FACS bins, we can reconstruct each variant's mean expression. 5) For binding values, by comparing binding as a function of ACE2 concentration, we calculate binding constants from per-variant titration curves.\r\n\r\nWe provide our duplicate library measurements at the level of individual variants within our library, which are described by unique molecular identifier barcodes downstream from the variant RBD coding sequence. We also provide decomposed single-mutant scores, which are the primary mutation scores we use in our analysis of the data. In each of these datasets, the binding score is a delta-log<sub>10</sub>(_K_<sub>D,app</sub>) metric from the variant titration curves, and the expression score is a delta-log(mean fluorescence intensity) measurement of cell surface expression. Both metrics are relative to the unmutated SARS-CoV-2 reference sequence phenotype, polarized such that a positive value indicates higher affinity or expression compared to unmutated SARS-CoV-2, and a negative value indicates decreased affinity or expression compared to unmutated SARS-CoV-2.\r\n\r\nSee the [preprint](https://www.biorxiv.org/content/10.1101/2020.06.17.157982v1) or [GitHub repository](https://github.com/jbloomlab/SARS-CoV-2-RBD_DMS) for additional information.",

They leveraged a traditional assay, the TOXCAT-$\\beta$-lactamase (T$\\beta$L) screen, and adapted it to deep mutational scanning studies (dsT$\\beta$L). The tested sequence is expressed in between a chimera of ToxR dimerization-dependent transcriptional activator of a chloramphenicol-resistance gene and $\\beta$-lactamase. In this construct, the membrane integration of target sequence determines the bacterial resistance to ampicillin and the self-association correlates with the chloramphenicol resistance. Besides, the orientation to the membrane of this chimera is also crucial for survival. The selection result was determined by deep-sequencing using Illumina.",

This construct was cloned under control of an inducible promoter and transformed into E. coli. Following restrictive transformation, the final library diversity was ~60,000 unique clones, corresponding to ~20 barcodes per missense variant. The barcoded coding region was amplified and analyzed by long-read MiSeq in order to associate barcodes with coding sequences. The resulting lookup table expedites subsequent quantification of variant frequencies.\r\nThis plasmid library was then transformed into yeast.

        "abstract_text": "alpha-Synuclein is a conformationally dynamic protein linked to a variety of neurodegenerative diseases, including Parkinson’s. Conformational transitions of this protein are believed to contribute to disease etiology, but the conformations that drive pathology remain unclear. To address this question, we screened an exhaustive library of alpha-synuclein missense variants for their toxicity in yeast, a well-validated cellular model for alpha-synuclein pathobiology. By examining the pattern of mutations that disrupts cellular toxicity, we were able to build a model for the structure of the toxic species.",
        "method_text": "A double-stranded DNA library based on human alpha-synuclein cDNA was produced by commercial oligonucleotide synthesis and assembly. The designed library encodes all single missense variants of alpha-synuclein, each encoded by a single codon. This library was cloned in frame with a C-terminal GFP fusion, and 26bp random barcodes were appended 3’ to the stop codon to facilitate repeated selection. This construct was cloned under control of an inducible promoter and transformed into E. coli. Following restrictive transformation, the final library diversity was ~60,000 unique clones, corresponding to ~20 barcodes per missense variant. The barcoded coding region was amplified and analyzed by long-read MiSeq in order to associate barcodes with coding sequences. The resulting lookup table expedites subsequent quantification of variant frequencies.\r\nThis plasmid library was then transformed into yeast. Selection was performed by inducing expression and collecting aliquots over time. Additional experiments were performed in yeast treated with small molecules. Finally, the expression level of each variant was estimated by cell sorting yeast cells based on the fluorescence of the GFP fusion.",

This was accomplished by overlap extension PCR using primers with degenerate NNK codons. Human Expi293F cells were transfected with the plasmid library diluted with a large excess of carrier plasmid to yield no more than one coding variant per cell. The cell culture was incubated with 1/20 (replicate 1) or 1/40 (replicate 2) dilution of a medium containing RBD fused to superfolder GFP (sfGFP) at its C-terminus. Cells were co-stained with anti-myc Alexa 647 to quantify surface ACE2 expression. Bound RBD was subsequently measured relative to surface ACE2 expression. Cells with the highest (top 15%; “nCoV-S-High” sort) and lowest (bottom 20%; “nCoV-S-Low” sort) levels of bound RBD-sfGFP relative to ACE2 expression were collected by fluorescence activated cell sorting (FACS). Transcripts in the sorted populations were extracted, diversified ACE2 regions were PCR amplified and Illumina sequenced.",

Here, we developed a deep mutational scanning framework that produces exhaustive maps for human missense variants by combining random codon mutagenesis and multiplexed functional variation assays with computational imputation and refinement. We applied this framework to four proteins corresponding to six human genes: UBE2I (encoding SUMO E2 conjugase), SUMO1 (small ubiquitin-like modifier), TPK1 (thiamin pyrophosphokinase), and CALM1/2/3 (three genes encoding the protein calmodulin). The resulting maps recapitulate known protein features and confidently identify pathogenic variation. Assays potentially amenable to deep mutational scanning are already available for 57% of human disease genes, suggesting that DMS could ultimately map functional variation for all human disease genes.",

To address this question, we screened an exhaustive library of alpha-synuclein missense variants for their toxicity in yeast, a well-validated cellular model for alpha-synuclein pathobiology. By examining the pattern of mutations that disrupts cellular toxicity, we were able to build a model for the structure of the toxic species.",

The designed library encodes all single missense variants of alpha-synuclein, each encoded by a single codon. This library was cloned in frame with a C-terminal GFP fusion, and 26bp random barcodes were appended 3’ to the stop codon to facilitate repeated selection. This construct was cloned under control of an inducible promoter and transformed into E. coli. Following restrictive transformation, the final library diversity was ~60,000 unique clones, corresponding to ~20 barcodes per missense variant. The barcoded coding region was amplified and analyzed by long-read MiSeq in order to associate barcodes with coding sequences. The resulting lookup table expedites subsequent quantification of variant frequencies.\r\n\r\nThis plasmid library was then transformed into yeast. Selection was performed by inducing expression and collecting aliquots over time. Additional experiments were performed in yeast treated with small molecules. Finally, the expression level of each variant was estimated by cell sorting yeast cells based on the fluorescence of the GFP fusion.",

Two human enhancers (ALDOB, ECR11) and one mouse enhancer (LTV1) were known to be active in mouse liver and therefore variants in these enhancers should show a measurable difference in transcription. The results were broadly consistent with evolutionary data and transcription factor binding sites, but were not always concordant demonstrating the importance of measuring the effect of enhancer variants directly.\r\n\r\nThis MaveDB entry describes the ALDOB enhancer data. Datasets for other enhancers described in the same publication are also available: [ECR11](https://www.mavedb.org/experiment/urn:mavedb:00000007-a/) [LTV1](https://www.mavedb.org/experiment/urn:mavedb:00000008-a/)",

Full-length enhancer haplotypes were assembled and cloned into tagged pGL4.23 plasmids. Each variant haplotype was tagged with a 20-bp sequence, with one tag per haplotype in almost all cases. Each single nucleotide change was present in at least 42 haplotypes. \r\n\r\nThe enhancers were injected into the mouse tail vein and mouse livers were harvested after 24h. RNA was isolated from fresh mouse livers, subjected to DNAseI treatment to remove any DNA contamination, reverse-transcribed into cDNA, and sequenced.\r\n\r\nTwo sets of sequencing reactions were performed. One used short Illumina reads (42 total cycles) to sequence the tag sequence used for quantifying each enhancer's activity. The other used subassembly synthetic long read sequencing to associate the tags with the full-length enhancer haplotypes.",

To address this question, we screened an exhaustive library of alpha-synuclein missense variants for their toxicity in yeast, a well-validated cellular model for alpha-synuclein pathobiology. By examining the pattern of mutations that disrupts cellular toxicity, we were able to build a model for the structure of the toxic species.",

The designed library encodes all single missense variants of alpha-synuclein, each encoded by a single codon. This library was cloned in frame with a C-terminal GFP fusion, and 26bp random barcodes were appended 3’ to the stop codon to facilitate repeated selection. This construct was cloned under control of an inducible promoter and transformed into E. coli. Following restrictive transformation, the final library diversity was ~60,000 unique clones, corresponding to ~20 barcodes per missense variant. The barcoded coding region was amplified and analyzed by long-read MiSeq in order to associate barcodes with coding sequences. The resulting lookup table expedites subsequent quantification of variant frequencies.\r\n\r\nThis plasmid library was then transformed into yeast. Selection was performed by inducing expression and collecting aliquots over time. Additional experiments were performed in yeast treated with small molecules. Finally, the expression level of each variant was estimated by cell sorting yeast cells based on the fluorescence of the GFP fusion.",

Here, we developed a deep mutational scanning framework that produces exhaustive maps for human missense variants by combining random codon mutagenesis and multiplexed functional variation assays with computational imputation and refinement. We applied this framework to four proteins corresponding to six human genes: UBE2I (encoding SUMO E2 conjugase), SUMO1 (small ubiquitin-like modifier), TPK1 (thiamin pyrophosphokinase), and CALM1/2/3 (three genes encoding the protein calmodulin). The resulting maps recapitulate known protein features and confidently identify pathogenic variation.

Conformational transitions of this protein are believed to contribute to disease etiology, but the conformations that drive pathology remain unclear. To address this question, we screened an exhaustive library of alpha-synuclein missense variants for their toxicity in yeast, a well-validated cellular model for alpha-synuclein pathobiology. By examining the pattern of mutations that disrupts cellular toxicity, we were able to build a model for the structure of the toxic species.",
        "method_text": "A double-stranded DNA library based on human alpha-synuclein cDNA was produced by commercial oligonucleotide synthesis and assembly. The designed library encodes all single missense variants of alpha-synuclein, each encoded by a single codon. This library was cloned in frame with a C-terminal GFP fusion, and 26bp random barcodes were appended 3' to the stop codon to facilitate repeated selection. This construct was cloned under control of an inducible promoter and transformed into E. coli. Following restrictive transformation, the final library diversity was ~60,000 unique clones, corresponding to ~20 barcodes per missense variant. The barcoded coding region was amplified and analyzed by long-read MiSeq in order to associate barcodes with coding sequences.

        "abstract_text": "The membrane-associated RING-CH (MARCH) proteins are E3 ubiquitin ligases that contain transmembrane (TM) domains and regulate the cell-surface levels of key immune-stimulatory ligands such as major histocompatibility complex (MHC) molecules and the T-cell costimulatory ligand CD86. Endogenous mammalian MARCHs act on these targets to regulate antigen presentation and activation of adaptive immunity, while virus-encoded homologs target the same molecules to evade immune responses. Substrate specificity is believed to be encoded in or near the membrane-embedded domains of MARCHs and the proteins they regulate, but exactly what sequences distinguish substrates from non-substrates is poorly understood. Here we examined the requirements for recognition of the costimulatory ligand CD86 by two different MARCH-family proteins, human MARCH1 and Kaposi’s sarcoma herpesvirus (KSHV) modulator of immune recognition (MIR)2, using a deep mutational scanning (DMS) approach. We identified a highly specific recognition surface in the hydrophobic core of the CD86 TM domain that is required by MARCH1 and prominently features a proline at position 254. In contrast, MIR2 requires no specific sequences in the CD86 TM domain but relies primarily on an aspartic acid at position 244 in the CD86 extracellular juxtamembrane region. Surprisingly, while MIR2 recognized CD86 with a TM domain composed entirely of valine, many different single-amino-acid substitutions in the context of the native TM sequence conferred MIR2 resistance. These results show that the human and viral proteins evolved completely different recognition modes for the same substrate and reveal that some TM sequences may be incompatible with MIR2 activity even when no specific recognition motif is required.",
        "method_text": "The DMS library was made using overlap PCR with primers (IDT) containing NNN mixed bases and cloned into pHAGE-eF1a-MCS-IRES-ZsGreen using T4 ligase (NEB). Ligation reactions were transformed into XL1-Blue E. coli and colonies counted to ensure each position had at least 200 transformants to provide good coverage of 64 possible DNA variants.  Colonies were washed directly from LB-Agar plates into LB broth and grown until cultures were turbid (~2 hours) before plasmid DNA was recovered by miniprep (Qiagen).  1 µg of DNA from each position was combined to provide a deep mutational scanning library with complete coverage along the CD86 TM domain.  \r\n\r\nLentivirus produced from the library was titrated to result in ~10-20% transduction efficiency of 300,000 HeLa cells resulting in 30-60,000 transduced cells in each replicate.  2 days post transduction, ZsGreen positive HeLa cells were sorted from each replicate.  These cells were expanded to fill one 6-well plate well (~1 million cells) before mRNA was harvested from half of the cells (Population I), with the remainder sorted for CD86 surface expression.  CD86 positive cells were again grown to confluence before mRNA was harvested from a third of the cells (Population II), with the remainder split in two and transduced with either MARCH1 or MIR2 transducing around half of the cells as measured by mCherry expression.  Cells were expanded to confluence and sorted on mCherry expression. This population was expanded and mRNA harvested from half of the cells (Population III).  The other half was incubated with 150 ng/ml of doxycycline for 48 hours to induce MARCH1/MIR2 expression.  Cells were stained for CD86 surface expression and cells containing CD86 variants that were resistant to MARCH1 or MIR2 recovered and expanded before mRNA was harvested (Population IV).\r\n\r\nEnrichment scores of Population II versus Population I were calculated to determine cell surface levels of variant CD86 molecules.

The fusion library was inserted into pQE-30 expression vectors and used to transform E. coli XL1 Blue.\r\n\r\nCells were sorted into eight bins using FACS Aria III cell sorter (BD Biosciences).

        "abstract_text": "Classical homocystinuria--characterized by excessive levels of total homocysteine in plasma--is caused by primarily-rare variants in the cystathionine-beta-synthase (CBS) gene. With early detection, existing therapies are highly effective, e.g., most patients respond to vitamin B6 therapy. Functional CBS variants, or deleterious variants that respond to vitamin B6, can be detected based on their ability restore growth in yeast cells lacking CYS4 (the yeast ortholog of CBS). Here we describe a comprehensive missense variant effect map for CBS.",
        "method_text": "We reimplemented a previously validated humanized yeast model (Kruger & Cox, PNAS, 1994), confirming that expression of human CBS from the hORFeome collection restores the ability of a yeast cys4&Delta; strain to grow without supplementation of glutathione. Coupling this functional complementation with our recently developed framework for exhaustively mapping functional coding variants (Weile & Sun et al, MSB, 2017), we attempted to test the functional impact as well as the vitamin B6 remediability of all possible missense CBS variants in parallel. \r\n\r\nFirst, we constructed a library of CBS variants using our previously described POPCode mutagenesis method (Weile & Sun et al, MSB, 2017). The variant library, initially generated as a pool of amplicons, was transferred en masse into the appropriate yeast expression vector via two steps of recombinational subcloning.  The resulting library of variant expression clones was then transformed en masse into the yeast cys4 mutant strain. \r\n\r\nNext, pools of transformed yeast cys4 mutant strains were grown competitively in cysteine-lacking medium supplemented with low (0, 1ng/ml) or high (400 ng/ml) concentrations of vitamin B6. Allele frequencies of CBS variants before and after selection were determined by next-generation sequencing. To ensure accuracy of allele frequency estimates, we following the TileSeq approach (Weile & Sun et al, MSB, 2017) in which sequencing is applied to a tiling set of ~100 nt segments of the gene library, enabling sequencing reads from both forward and reverse strands of each template cluster on the flow cell.  Sequencing was performed such that both forward and reverse strands of each nucleotide position were covered by ~2M reads. \r\n\r\nThe sequence analysis code can be found at https://bitbucket.org/rothlabto/tileseq_package\r\n\r\nSee https://www.biorxiv.org/content/early/2018/11/19/473983 for more information.",
