Calcitonin and Related Receptors

Calcitonin and related receptors are a family of G-protein-coupled receptors that comprises eight subtypes; CT, AMY1, AMY2, AMY3, CALCR, CGRP, AM1 and AM2. The main function of CT receptors is to inhibit bone reabsorption and enhance calcium excretion by the kidneys.

Calcitonin and related receptors are a family of G-protein-coupled receptors that comprises eight subtypes; CT, AMY1, AMY2, AMY3, CALCR, CGRP, AM1 and AM2. The receptors have a wide biological distribution; high concentrations are found in the brain, lung, liver, heart and spleen with lower expression levels present in the testes, gastrointestinal tract and thyroid.

The main function of CT receptors is to inhibit bone reabsorption and enhance calcium excretion by the kidneys. AMY receptors are heterodimers of the CT receptor and receptor activating modifying proteins (RAMP) 1-3, which have been implicated in type II diabetes pathology. The CALCRL receptor alone is non-functioning, but forms heterodimers with RAMPs to form the CGRP (CALCRL with RAMP1), AM1 (CALCRL with RAMP2) and AM2 (CALCRL with RAMP3) receptors. Their main function is inducing vasodilation, which causes hypotension. The CGRP receptor has also recently been implicated in the pathogenesis of migraine.

CT and CALCRL form heterodimers with RAMP1-3, forming additional calcitonin related receptors; AMY1, AMY2, AMY3, CGRP, AM1 and AM2. (AMY1 = CT + RAMP1, AMY2 = CT + RAMP2, AMY3 = CT + RAMP3, CGRP = CALCRL + RAMP1, AM1 = CALCRL + RAMP2, AM2 = CALCRL + RAMP3)
