Calcium-sensing receptor

Calcium-sensing receptor

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.cite journal | author = D'Souza-Li L | title = The calcium-sensing receptor and related diseases | journal = Arquivos brasileiros de endocrinologia e metabologia | volume = 50 | issue = 4 | pages = 628–39 | year = 2006 | pmid = 17117288 | doi = 10.1590/S0004-27302006000400008 | issn = ]

Pathology

Mutations that inactivate CASR cause familial hypocalciuric hypercalcemia (FHH),cite journal | author = Pidasheva S, Canaff L, Simonds WF, Marx SJ, Hendy GN | title = Impaired cotranslational processing of the calcium-sensing receptor due to signal peptide missense mutations in familial hypocalciuric hypercalcemia | journal = Hum. Mol. Genet. | volume = 14 | issue = 12 | pages = 1679–90 | year = 2005 | pmid = 15879434 | doi = 10.1093/hmg/ddi176 | issn = ] whereas mutations that activate CASR are the cause of autosomal dominant hypocalcemia.cite journal | author = Mancilla EE, De Luca F, Baron J | title = Activating mutations of the Ca2+-sensing receptor | journal = Mol. Genet. Metab. | volume = 64 | issue = 3 | pages = 198–204 | year = 1998 | pmid = 9719629 | doi = 10.1006/mgme.1998.2716 | issn = ] An alternatively spliced transcript variant encoding 1088 aa has been found for this gene, but its full-length nature has not been defined.

Therapeutic application

The drug cinacalcet is an allosteric modifier of the calcium-sensing receptor.cite journal | author = Torres PU | title = Cinacalcet HCl: a novel treatment for secondary hyperparathyroidism caused by chronic kidney disease | journal = Journal of renal nutrition : the official journal of the Council on Renal Nutrition of the National Kidney Foundation | volume = 16 | issue = 3 | pages = 253–8 | year = 2006 | pmid = 16825031 | doi = 10.1053/j.jrn.2006.04.010 | issn = ]
