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 and in the cleavage of peptides bound to major histocompatibility complex class II molecules of antigen presenting cells. May have a role in angiogenesis By similarity. May serve as a receptor for bovine coronavirus (BCV) in a species-specific manner. Ref.2

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.

Domain

Amino acids 647-837 are essential to mediate susceptibility to infection with TGEV (in human/bovine chimeric studies). Ref.2

Sequence similarities

Belongs to the peptidase M1 family.
