About PGA4

Cytogenetic location: 11q12.2 Genomic coordinates (GRCh38): 11:61,222,347-61,231,694 (from NCBI)

This gene has 8 transcripts (splice variants), 165 orthologues and 9 paralogues. Restricted expression toward stomach (RPKM 23688.7).

Summary

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]
