FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Carboxypeptidase N is a plasma metallo-protease that cleaves basic amino acids from the C terminal of peptides and proteins. The enzyme is important in the regulation of peptides like kinins and anaphylatoxins, and has also been known as kininase-1 and anaphylatoxin inactivator. This enzyme is a tetramer comprised of two identical regulatory subunits and two identical catalytic subunits; this gene encodes the catalytic subunit. Mutations in this gene can be associated with angioedema or chronic urticaria resulting from carboxypeptidase N deficiency. [provided by RefSeq, Jul 2008]
PHENOTYPE: Mice homozygous for a knock-out allele are highly susceptible to lethal anaphylactic shock caused by acute complement activation when administered cobra venom factor or C5a complement. [provided by MGI curators]
