malfunction
physiological function
malfunction
among mice genetically deficient in either carboxypeptidase B2 (Cpb2) or carboxypeptidase N (Cpn), in a model of hemolytic-uremic syndrome, Cpb2-/- mice have the worst disease, followed by Cpn-/- mice, with wild-type mice being the most protected. This model is driven by complement component C5a, and shows that carboxypeptidase B2 is important in inactivating complement component C5a. Cpn-/- mice are generated by disruption of complement component Cpn1. When mice are challenged acutely with cobra venom factor, the reverse phenotype is observed. Cpn-/- mice have markedly worse disease than Cpb2-/- mice, and wild-type mice are resistant
malfunction
the knockdown of cpn1 by morpholino injection impairs the growth of intersegmental vessels and caudal vein plexus. Loss of cpn1 affects the expression of the vascular markers flt4, mrc1, flk, stabilin, and ephrinb2
physiological function
carboxypeptidase N is responsible for systemic inactivation of complement component C3a and C5a
physiological function
cpn1 is involved in vascular development of zebrafish
physiological function
the enzyme removes C-terminal basic amino acids from bioactive peptides and proteins, thereby inactivating them

-
the enzyme contains seven potential N-linked glycosylation sites and a threonine/serine-rich region which is a potential site for attachment of O-linked carbohydrate
side-chain modification
-
the carbohydrate is primarily attached to the larger subunit, representing 28% of its weight. Two forms detected in isoelectric focusing with pI of 3.8 and 4.3. The difference is attributed to differences in sialic acid content of the two forms
side-chain modification
-
the 90000 Da subunit contains carbohydrate, no carbohydrate is detected in the subunits of MW 50000 Da and 30000 Da
