Crystal structure of the human carboxypeptidase N (Kininase I) catalytic domain

Template:ABSTRACT PUBMED 17157876

Disease

[CBPN_HUMAN] Defects in CPN1 are the cause of carboxypeptidase N deficiency (CPND) [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.^[1]

Function

[CBPN_HUMAN] 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.

About this Structure
