Summaries for CPA1 Gene

Entrez Gene Summary for CPA1 Gene

  • This gene encodes a member of the carboxypeptidase A family of zinc metalloproteases. This enzyme is produced in the pancreas and preferentially cleaves C-terminal branched-chain and aromatic amino acids from dietary proteins. This gene and several family members are present in a gene cluster on chromosome 7. Mutations in this gene may be linked to chronic pancreatitis, while elevated protein levels may be associated with pancreatic cancer. [provided by RefSeq, Jan 2015]

GeneCards Summary for CPA1 Gene

CPA1 (Carboxypeptidase A1) is a Protein Coding gene. Diseases associated with CPA1 include Pancreatitis and Borna Disease. Among its related pathways are Collagen chain trimerization and Pancreatic secretion. Gene Ontology (GO) annotations related to this gene include metallocarboxypeptidase activity and exopeptidase activity. An important paralog of this gene is CPA2.

UniProtKB/Swiss-Prot for CPA1 Gene

  • Carboxypeptidase that catalyzes the release of a C-terminal amino acid, but has little or no action with -Asp, -Glu, -Arg, -Lys or -Pro.
