The calcium-sensing receptor (CaSR) is a G-protein coupled receptor which senses extracellular levels of calcium ion. In the parathyroid gland, the calcium-sensing receptor controls calcium homeostasis by regulating the release of parathyroid hormone.[1]
Pathology
Mutations that inactivate CASR cause familial hypocalciuric hypercalcemia (FHH),[2] whereas mutations that activate CASR are the cause of autosomal dominant hypocalcemia.[3] An alternatively spliced transcript variant encoding 1088 aa has been found for this gene, but its full-length nature has not been defined.[4]
Therapeutic application
The drug cinacalcet is an allosteric modifier of the calcium-sensing receptor.[5]
