Gastrin I (1-14) (human)

Gastrin I (1-14), human, is a fragment of Gastrin I which is an endogenous peptide hormone. It is primarily expressed in the gut and stimulates gastric acid secretion by binding to the CCK2/Gastrin receptors on parietal cells of the stomach. Gastrin I stimulates lectin-like protein Reg expression via activation of PKC and RhoA.
