Calcitonin gene-related peptide

A 37-amino acid peptide derived from the calcitonin gene. It occurs as a result of alternative processing of mRNA from the calcitonin gene. The neuropeptide is widely distributed in the brain, gut, perivascular nerves, and other tissue. The peptide produces multiple biological effects and has both circulatory and neurotransmitter modes of action. In particular, it is a potent endogenous vasodilator.

As a potential drug, it has demonstrated in preclinical studies a profile that could make it an ideal anti-asthmatic drug candidate with bronchodilatory, bronchoprotecting and anti-inflammatory properties.
