Methods that need multiple sequence alignments can be slow because an alignment must be built for each protein, whereas this approach works from single sequences. If the timing holds, variant effects could be scored for an entire proteome on a single graphics card, making large-scale screening cheaper in computing and energy.","findings":["Embeddings from ProtT5 predicted residue conservation almost as accurately from single sequences as ConSeq using alignments (MCC 0.596 vs. 0.608).","On 39 DMS experiments, VESPA was competitive with state-of-the-art methods that use alignments, and no method outperformed all others consistently or significantly.","The authors conclude embedding-based methods are competitive with alignment-based ones at a fraction of the computing and energy cost."],"terms":[{"term":"SAV (single amino acid variant)","means":"A change in a protein in which one amino acid is swapped for another, usually due to a single mutation in the gene."},{"term":"proteome","means":"The full set of proteins made by an organism; for humans, about 20,000 proteins."},{"term":"Nvidia Quadro RTX 8000","means":"A professional graphics processing unit (GPU) often used for demanding computing tasks such as running deep learning models."}],"basis":"abstract","abstractFrom":"crossref","model":"claude-sonnet-5-5","writtenAt":"2026-10-13T12:46:48.844Z","version":"context/0.2"},"summary":{"status":"written","at":"2026-10-13T12:46:48.844Z","attempts":1,"model":"claude-sonnet-5-5","why":null},"note":"Machine-written context to help a reader: it is not evidence, it moves no number, and it may be wrong.
