Safety First: Input Screening for Protein Design Tools
bioRxiv preprint, 2026 · Nuclear Threat Initiative
AI protein design tools can produce novel sequences that similarity-based screening misses. BioScreen screens the target instead: a database of 14,541 potentially harmful human proteoforms, classified by risk level, combined with embedding-based screening using the ESM-C protein language model. It reaches F1 > 97% on variants of known targets and tells benign mutations apart from damaging ones where BLASTP does not.
