Summation

The calcitonin gene-related peptides alpha-CGRP and beta-CGRP (Morris HR et al, 1984, Steenbergh PH et al, 1985 respectively) are members of the calcitonin family of peptides and are produced in both peripheral and central neurons. They are the most potent peptide vasodilators and can function in the transmission of pain. Their effects are mediated by binding to the CGRP1 receptor (CL) (Aiyar N et al, 1996). CGRP receptors are complexes between CL and receptor activity modifying protein 1 (RAMP1) (Kuwasako K et al, 2004). The activity of the receptor is mediated by coupling to the G protein alpha s subunit, which stimulates adenylyl cyclase which can increase intracellular cAMP levels (Van Valen et al, 1990).
