Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Val114 of human CGRP protein.
Background
Calcitonin gene-related peptide (CGRP) is a peptide of 37 amino acids that belongs to the calcitonin (CT) family of peptide hormones. The calcitonin gene (CALCA) encodes a number of tissue-specific peptides through alternative splicing of mRNA transcripts and precursor protein cleavage (1). Both calcitonin and α-CGRP are produced from the CALCA gene, while a second gene (CALCB) encodes the related β-CGRP protein (2). α-CGRP and β-CGRP share similar activities and differ by three or fewer residues depending on the species (3). The CGRP peptide activates a heterotrimeric receptor complex that consists of the seven transmembrane-spanning calcitonin receptor-like receptor, the single transmembrane-spanning RAMP1 protein, and an intracellular receptor component protein (4,5). CGRP is expressed in the central and peripheral nervous system in mammals, where it exhibits several important physiologic roles. Research studies demonstrate that CGRP is a potent vasodilatator (6) and a modulator of acetylcholine receptor function at neuromuscular junctions (7). Additional studies indicate that CGRP peptide is involved in feeding (8) and inflammatory pain (9). CGRP peptide also plays a key role in the physiology of migraine attacks. Specifically, CGRP peptide levels increase during acute migraine attacks, which can be ameliorated through treatment with CGRP antagonists (10).
