Material Safety Data Sheet (MSDS)

Originally identified in Heloderma horridum horridum (Mexican beaded lizard), exendin-3 is in the glucagon family. Exendin 3 stimulates vasoactive intestinal peptide (VIP) receptors in high concentrations. This leads to increased cAMP levels and amylase secretion in the pancreas. However, low exendin-3 exposure only increases cAMP levels.

In applications, exendin-3 was found to induce hypotension by relaxation of cardiac, smooth muscle. Using a tag, exendin-3 is being investigated as a stable agonist for GLP1R to detect insulinomas, a pancreatic B cell-derived cancer with high GLP1R expression. Exendin 3 has also been used on mouse models to assess its effect on glucose-stimulated insulin secretion in glucagon receptor knockout (Gcgr-/-) backgrounds. Understanding the interplay between exendin 3 and metabolism could provide new insights into the obesity crisis.
