It interacts with the CGRP protein, whose expression is related to migraine attacks. Conversely, CGRP is derived from dorsal root ganglion when synthesized in the dorsal horn of the spinal cord and may be linked to the transmission of pain. It interacts with the CGRP protein expressed during an attack. This is of particular concern, as females (16.6%) are more genetically predisposed to migraine than are males (7.5%). It interacts by blocking the CGRP receptor. PMID 8897024; Einzelnachweise ↑ Rosenfeld, M.G. De CGRP-receptor heeft drie subeenheden: receptoractiviteit-modificerend proteïne 1 (RAMP1), calcitonine-achtige receptor (CLR) en receptorcomponentproteïne (RCP). The main side effects are injection site reactions.[40][41]. Die CGRP-vermittelte Vasodilatation ist vermutlich ein wichtiger pathogenetischer Mechanismus bei der Entstehung der Migräne. Calcitonin-Gene-Related-Peptide-Rezeptorantagonisten (kurz CGRP-Rezeptorantagonisten oder CGRP-Antagonisten) sind Arzneistoffe, welche die Wirkung des Calcitonin Gene-Related Peptide (CGRP) durch Blockade seines Rezeptors, dem Calcitonin-Gene-Related-Peptide-Rezeptor, hemmen.

[9] Because of these characteristics, it has been said that CGRP functions more as a neurotransmitter than a hormone. CGRP is derived mainly from the cell bodies of motor neurons when synthesized in the ventral horn of the spinal cord and may contribute to the regeneration of nervous tissue after injury. In smooth muscle of neurovascular region, the elevation of cAMP upon CGRP activation results in vasodilation of the blood vessel. Antibodies are proteins that counter or interfere with very specific parts of another protein or the site where a protein is supposed to bind to the receptor.
