描述：Helodermin (exendin-2) was originally isolated from the venom of Gila monster (Heloderma suspectum). A high degree of sequence similarities to secretin, VIP, PHI, and GRF from mammal and bird was observed over the entire N-terminal (1-27) sequence. The isolation of helodermin was the first demonstration of the existence of a secretin/VIP-related peptide in an animal that is neither mammal nor bird. Among all known VIP-related peptides, helodermin was the most potent in stimulating cAMP production by NCI-H345 cell line.
