SARS-CoV-2 relevant PROSITE motifs

PROSITE consists of documentation entries describing protein domains, families and functional sites as well as associated patterns and profiles to identify them [More... / References / Commercial users ].
PROSITE is complemented by ProRule , a collection of rules based on profiles and patterns, which increases the discriminatory power of profiles and patterns by providing additional information about functionally and/or structurally critical amino acids [More...].


Release 2025_01 of 05-Feb-2025 contains 1952 documentation entries, 1311 patterns, 1399 profiles and 1415 ProRule.

Quick Scan mode of ScanProsite
Quickly find matches of your protein sequences to PROSITE signatures (max. 10 sequences). [?] Examples

For UniProtKB/TrEMBL accessions/identifiers, only those of entries belonging to reference proteomes are accepted.

Exclude motifs with a high probability of occurrence from the scan
