Summary: This gene encodes carboxypeptidase A, a zinc-dependent metalloprotease that cleaves peptide bonds at the C-terminus of protein substrates. The encoded preproprotein undergoes proteolytic activation to generate a mature, functional enzyme. This gene is expressed in pancreas, the encoded protein is a major component of digestive enzymes secreted by pancreas and plays an important role in the process of digestion. This gene is located in a cluster of related carboxypeptidase genes on chromosome 6. [provided by RefSeq, Jan 2016]

What's a GeneRIF?

We generated a novel CPA1 N256K knock-in mouse strain, which carries the most frequently occurring human CPA1 p.N256K mutation in the mouse Cpa1 gene. The CPA1 N256K mice develop spontaneous and progressive chronic pancreatitis and exhibit signs of endoplasmic reticulum stress in their pancreas.

Data indicate that AAV-mediated latexin transduction or administration of a small molecule carboxypeptidase A inhibitor significantly reduced acetone-evoked nociceptive behavior after SNI.
Title: Nerve injury evoked loss of latexin expression in spinal cord neurons contributes to the development of neuropathic pain.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
