CCK2, Gastrin I (human), Gastrin I, human, Gastrin I
Gastrin I (human) is an endogenous gastric peptide that stimulates pepsinogen and gastric acid secretion by activating the cholecystokinin B (CCK2) receptor. This peptide is a valuable research tool for studying gastrointestinal physiology, receptor signaling, and related disorders in both in vitro and in vivo experimental models.
