Zero-shot prediction of protein variant effects with language models
ESM-1v is an ensemble of five 650M-parameter protein language models trained to predict the functional consequences of single amino acid mutations across thousands of diverse proteins without training on experimental labels.
State-of-the-art zero-shot variant effect prediction across 41 deep mutational scanning datasetsEnsemble of five distinct models trained on UniRef90 with different random seedsCaptures epistatic and structural constraints directly from evolutionary sequencesStandard benchmark baseline in computational biology for mutation scoring
