Calcitonin gene-related peptide (CGRP), adrenomedullin (AM) and adrenomedullin 2 (AM2) are related peptides, which are potent vasodilators. The receptors for these peptides are unusual, comprising a G-protein-coupled receptor (GPCR) with receptor activity-modifying proteins (RAMPs). The GPCR, the calcitonin receptor-like receptor (CLR), forms a CGRP receptor with RAMP1, (the CGRPR), whereas CLR with RAMP2 or RAMP3 forms two subtypes of adrenomedullin receptor (AM1 and AM2 receptors). CGRP is also a potent agonist at the AMY1(a) receptor, a heterodimer between the calcitonin receptor (CTR) and RAMP1. This article covers the pharmacology of these receptors, their structure, distribution, and potential involvement in disease.
