NCIt definition : Carboxypeptidase N catalytic chain (458 aa, 52 kDa) is encoded by the human CPN1
gene. This protein is involved in carboxypeptidase activity targeting circulating
bioactive peptides.;
NCIt note : Carboxypeptidase N is a tetramer comprised of two identical catalytic chains (carboxypeptidase
N catalytic chain; CPN1) and two identical inactive regulatory chains (carboxypeptidase
N subunit 2; CPN2).;
