It is complemented by ProRule, a rule collection that enhances the discriminatory power of these profiles and patterns by providing additional information about amino acids critical for function and\/or structure. Together, PROSITE motifs and ProRules are used to annotate domains and features in UniProtKB\/Swiss-Prot entries. Since the onset of the COVID-19 pandemic, PROSITE has contributed to SARS-CoV-2 research by leveraging existing tools and by developing new profiles and ProRules for SARS-CoV-2 protein domains. A newly developed profile has also uncovered a link between coregulators of two transcription factor families: POU2F and NF-\u03baB. ProRule has been updated to incorporate the ChEBI ontology to describe chemical ligands and the Rhea reference vocabulary for biochemical reaction annotation. Predicted tridimensional (3D) structures from AlphaFold are now regularly used to define domain boundaries during profile construction. ScanProsite has been enhanced to allow users to visualize motif matches on AlphaFold-predicted structures. In addition, the original pfsearch code has been fully rewritten and optimized to make efficient use of modern multi-core processors, with a new heuristic implemented to further improve performance.<\/jats:p>","DOI":"10.1093\/nar\/gkaf1188","type":"journal-article","created":{"date-parts":[[2025,11,20]],"date-time":"2025-11-20T10:13:00Z","timestamp":1763633580000},"page":"D451-D458","source":"Crossref","is-referenced-by-count":28,"title":["The
