Description
Product Characteristics: 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.,PGA5,Pg5,Cancer,Signal Transduction,Cell Biology & Developmental Biology,Ubiquitin,Endocrine & Metabolism,PGA5
Target Information: Shows particularly broad specificity\, although bonds involving phenylalanine and leucine are preferred, many others are also cleaved to some extent
