MGI Phenotype

FUNCTION: This gene encodes the peptide hormone gastrin, which stimulates gastric acid secretion, proliferation, cell migration and angiogenesis, as well as inhibits apoptosis. The encoded preproprotein undergoes proteolytic processing to generate multiple gastrin peptides differing in size. Mice lacking the encoded protein exhibit a decrease in the number of parietal cells, achlorohydria and a decrease in the colonic proliferation. [provided by RefSeq, Nov 2015]
PHENOTYPE: Homozygotes for targeted null alleles exhibit an absence of gastric acid secretion, alterations in gastric architecture, fasting hypoglycemia with impaired glucagon response, and increased susceptibility to azoxymethane-induced colon tumors. [provided by MGI curators]
