| Bioactivity | Exendin-3 is a biologically active peptides isolated from venoms of the Gila monster lizards, Heloderma horridurn. | ||||||
| Invitro | Exendin-3 interacts with at least two receptors on guinea pig pancreatic acini; at high concentrations (>100 nM) the peptide interacts with VIP receptors, thereby causing a large increase in cAMP and stimulating amylase release; at lower concentrations (0.1-3 nM) the peptide interacts with a putative exendin receptor, thereby causing a smaller increase in cAMP of undetermined function[1]. | ||||||
