PGA3 Gene (Protein Coding)

Pepsinogen A3

GC11P061203
GIFtS:
34
This gene encodes a protein precursor of the digestive enzyme pepsin, a member of the peptidase A1 family of endopeptidases. The encoded precursor is secreted by gastric chief cells and undergoes autocatalytic cleavage in acidic conditions to form the active enzyme, which functions in the digestion of dietary proteins. This gene is found in a cluster of related genes on chromos... See more...

Summaries for PGA3 Gene

Entrez Gene Summary for PGA3 Gene

  • This gene encodes a protein precursor of the digestive enzyme pepsin, a member of the peptidase A1 family of endopeptidases. The encoded precursor is secreted by gastric chief cells and undergoes autocatalytic cleavage in acidic conditions to form the active enzyme, which functions in the digestion of dietary proteins. This gene is found in a cluster of related genes on chromosome 11, each of which encodes one of multiple pepsinogens. Pepsinogen levels in serum may serve as a biomarker for atrophic gastritis and gastric cancer. [provided by RefSeq, Jul 2015]

GeneCards Summary for PGA3 Gene

PGA3 (Pepsinogen A3) is a Protein Coding gene. Diseases associated with PGA3 include Atrophic Gastritis and Gastritis. Among its related pathways are Surfactant metabolism and Collagen chain trimerization. Gene Ontology (GO) annotations related to this gene include aspartic-type endopeptidase activity. An important paralog of this gene is PGA4.

UniProtKB/Swiss-Prot Summary for PGA3 Gene

  • Shows particularly broad specificity; although bonds involving phenylalanine and leucine are preferred, many others are also cleaved to some extent.
