The Cleavage Atlas collects proteolytic cleavage sites observed in public mass-spectrometry proteomics data (PRIDE/ProteomeXchange). Each identifier names a single peptide bond in a UniProtKB protein, independent of which protease cleaves it: the UniProtKB accession, an optional isoform number, and the P1 residue position (Schechter-Berger numbering on the full precursor sequence, Met1 = 1). The bond named is the one between residue P1 and residue P1+1.

Comment

The accession + P1 key formalises what MEROPS, TopFIND and TermineR already use internally to join cleavage records, so a MEROPS cleavage, a TopFIND cleavage, a UniProt "Site" cleavage feature and an atlas observation map to the same identifier. Unlike those keys it does not include the protease. P1 = 0 and P1 = sequence length are protein termini, not bonds, and are not valid. No isoform suffix means the UniProt canonical isoform.

Pattern for Local Unique Identifiers
Local unique identifiers in Cleavage Atlas should match this regular expression:
^([OPQ][0-9][A-Z0-9]{3}[0-9]|[A-NR-Z][0-9]([A-Z][A-Z0-9]{2}[0-9]){1,2})(-[0-9]+)?_[1-9][0-9]*$

Pattern for CURIES
Compact URIs (CURIEs) constructed from Cleavage Atlas should match this regular expression:
^cleavageatlas:([OPQ][0-9][A-Z0-9]{3}[0-9]|[A-NR-Z][0-9]([A-Z][A-Z0-9]{2}[0-9]){1,2})(-[0-9]+)?_[1-9][0-9]*$
Example CURIEs

cleavageatlas:P15692-4_26
cleavageatlas:P15692-9_141
cleavageatlas:Q8N2S1-2_20
Providers

A provider turns a local unique identifiers from a resource into a URI. Many providers are also resolvable as URLs (i.e., they can be used in a web browser).

The local unique identifier P01009_382 is used to demonstrate the providers available for Cleavage Atlas. Some providers may use a different example, which is displayed in the table below. A guide for curating additional providers can be found here.
