Protein Name: Xaa-Pro aminopeptidase 1

UniprotKB/SwissProt ID: Q9NQW7 (Q9NQW7)

Gene Name: XPNPEP1

Organism: Homo sapiens (Human)

Function: Metalloaminopeptidase that catalyzes the removal of a penultimate prolyl residue from the N-termini of peptides, such as Arg-Pro-Pro (PubMed:11106490, PubMed:18515364, PubMed:35165443). Contributes to the degradation of bradykinin (PubMed:11106490)

Other Modifications: View all modification sites in dbPTM

Protein Subcellular Localization: Cytoplasm, cytosol
