Product Name Big Gastrin-1, human
Purity HPLC>95%
Description Large gastrin is also called gastrin-34. The secretion of gastrin is caused by food intake and causes the release of gastric acid in the stomach. Secreted by G cells in the gastric mucosa, it is one of the main bioactive forms of gastrin in tissues and plasma (the other bioactive form is gastrin-17 or small gastrin-Cat#AS-20750). Both gastrin-17 and gastrin-34 are carboxy amidated and partially tyrosine sulfated. The binding of gastrin to CCK2/gastrin receptor requires carboxy amidation, but binding to the receptor does not require sulfation. Gastrin binds to the CCK2/gastrin receptor on the parietal cells, causing the parietal cells to secrete hydrochloric acid (HCl), and stimulates the expression of lectin-like protein Reg by activating PKC and RhoA. Gastrin also plays a role in the release of histamine and pepsinogen.
