Summaries for CPA3 Gene

Entrez Gene Summary for CPA3 Gene

  • Three different forms of human pancreatic procarboxypeptidase A have been isolated. This gene encodes a form which is obtained as a binary complex of a procarboxypeptidase A with proproteinase E and functions as a secretory granule metalloexopeptidase. [provided by RefSeq, Jan 2009]

GeneCards Summary for CPA3 Gene

CPA3 (Carboxypeptidase A3 (Mast Cell)) is a Protein Coding gene. Among its related pathways are Biosynthesis of the N-glycan precursor (dolichol lipid-linked oligosaccharide, LLO) and transfer to a nascent protein and Pancreatic secretion. GO annotations related to this gene include metallocarboxypeptidase activity. An important paralog of this gene is CPA2.
