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.

GeneCards Summary for CALCR Gene
CALCR (Calcitonin Receptor) is a Protein Coding gene. Diseases associated with CALCR include Osteoporosis and Pigmented Villonodular Synovitis. Among its related pathways are Signaling by GPCR and RANK Signaling in Osteoclasts. GO annotations related to this gene include G-protein coupled receptor activity and transmembrane signaling receptor activity. An important paralog of this gene is CALCRL.
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.
