Summaries for CPE Gene

Entrez Gene Summary for CPE Gene

  • This gene encodes a member of the M14 family of metallocarboxypeptidases. The encoded preproprotein is proteolytically processed to generate the mature peptidase. This peripheral membrane protein cleaves C-terminal amino acid residues and is involved in the biosynthesis of peptide hormones and neurotransmitters, including insulin. This protein may also function independently of its peptidase activity, as a neurotrophic factor that promotes neuronal survival, and as a sorting receptor that binds to regulated secretory pathway proteins, including prohormones. Mutations in this gene are implicated in type 2 diabetes. [provided by RefSeq, Nov 2015]

GeneCards Summary for CPE Gene

CPE (Carboxypeptidase E) is a Protein Coding gene. Diseases associated with CPE include Hyperproinsulinemia and Gas Gangrene. Among its related pathways are Peptide hormone metabolism and Allograft rejection. GO annotations related to this gene include cell adhesion molecule binding and carboxypeptidase activity. An important paralog of this gene is CPXM2.

UniProtKB/Swiss-Prot for CPE Gene

  • Removes residual C-terminal Arg or Lys remaining after initial endoprotease cleavage during prohormone processing. Processes proinsulin.
