{"prefix":"cleavageatlas","name":"Cleavage Atlas","description":"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.","pattern":"^([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]*$","uri_format":"https://cleavageatlas.com/site/$1","providers":[],"homepage":"https://cleavageatlas.com","contact":{"name":"Rens de Groot","orcid":"0000-0002-1044-9499","email":"R.deGroot@ucl.ac.uk","github":"rensdg-code"},"example":"P01009_382","example_extras":["P15692-4_26","P15692-9_141","Q8N2S1-2_20"],"license":"CC0-1.0","deprecated":false,"mappings":{},"synonyms":[],"keywords":["mass spectrometry","proteomics"],"publications":[],"appears_in":[],"depends_on":[],"namespace_in_lui":false,"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.
