catalytic activity:Release of a C-terminal basic amino acid, preferentially lysine.,cofactor:Binds 1 zinc ion per subunit.,disease:Defects in CPN1 are the cause of carboxypeptidase N deficiency [MIM:212070]. Patients affected present some combination of angioedema or chronic urticaria, as well as hay fever or astma, and have also slightly depressed serum carboxy peptidase N, suggestive of autosomal recessive inheritance of this disorder.,function:Protects the body from potent vasoactive and inflammatory peptides containing C-terminal Arg or Lys (such as kinins or anaphylatoxins) which are released into the circulation.,similarity:Belongs to the peptidase M14 family.,subunit:Tetramer of two catalytic chains and two glycosylated inactive chains.,tissue specificity:Synthesized in the liver and secreted in plasma.,
Secreted, extracellular space.
Synthesized in the liver and secreted in plasma.
