General annotation (Comments)

Function

Broad specificity aminopeptidase. Plays a role in the final digestion of peptides generated from hydrolysis of proteins by gastric and pancreatic proteases. May be involved in the metabolism of regulatory peptides of diverse cell types, responsible for the processing of peptide hormones, such as angiotensin III and IV, neuropeptides, and chemokines and involved the cleavage of peptides bound to major histocompatibility complex class II molecules of antigen presenting cells. May have a role in angiogenesis By similarity.

Catalytic activity

Release of an N-terminal amino acid, Xaa-|-Yaa- from a peptide, amide or arylamide. Xaa is preferably Ala, but may be most amino acids including Pro (slow action). When a terminal hydrophobic residue is followed by a prolyl residue, the two may be released as an intact Xaa-Pro dipeptide.

Cofactor

Binds 1 zinc ion per subunit By similarity.

Subunit structure

Homodimer By similarity.

Subcellular location

Membrane; Single-pass type II membrane protein.

Post-translational modification

Sulfated By similarity.

Sequence similarities

Belongs to the peptidase M1 family.
