Calcitonin gene-related peptide (CGRP) is a 37-aa neuropeptide produced by tissue specific processing of the calcitonin gene, e.g. CGRP is the major product in neural tissues. CGRP is released by motor neurons where it exerts a long-lasting vasodilator effect on skeletal muscle fibers. CGRP binds to CGRP receptors on pancreatic beta cells, which induces plasma levels of pancreatic enzymes.Human: H-Ala-Cys-Asp-Thr-Ala-Thr-Cys-Val-Thr-His-Arg-Leu-Ala-Gly-Leu-Leu-Ser-Arg-Ser-Gly-Gly-Val-Val-Lys-Asn-Asn-Phe-Val-Pro-Thr-Asn-Val-Gly-Ser-Lys-Ala-Phe-NH2 (Cys2-Cys7) or H-ACDTATCVTHRLAGLLSRSGGVVKNNFVPTNVGSKAF-NH2 (Cys2-Cys7)
