Previous GeneCards Identifiers for CALCR Gene
This gene encodes a high affinity receptor for the peptide hormone calcitonin and belongs to a subfamily of seven transmembrane-spanning G protein-coupled receptors. The encoded protein is involved in maintaining calcium homeostasis and in regulating osteoclast-mediated bone resorption. Polymorphisms in this gene have been associated with variations in bone mineral density and onset of osteoporosis. Alternate splicing results in multiple transcript variants.

UniProtKB/Swiss-Prot for CALCR Gene
This is a receptor for calcitonin. The activity of this receptor is mediated by G proteins which activate adenylyl cyclase. The calcitonin receptor is thought to couple to the heterotrimeric guanosine triphosphate-binding protein that is sensitive to cholera toxin.
Calcitonin and related receptors are a family of G-protein-coupled receptors that comprises of 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.
