CASR (calcium sensing receptor) is a 7 transmembrane (7TM) receptor belonging to the family 3 (also known as family C) of the G-protein-coupled receptors (GPCRs). Structurally they are composed of 4 elements; an N-terminal signal peptide; a large hydrophilic extracellular agonist-binding region; a region containing 7TM domains; and a C-terminal cytoplasmic domain of variable length. Family 3 members include the metabotropic glutamate receptors (mGluRs), the extracellular calcium-sensing receptors (CASRs), the gamma-amino-butyric acid (GABA) type B receptors, and the vomeronasal type-2 receptors.  These GPCRs regulate many important physiological processes and many of them are promising targets for drug development. CASR is expressed in the parathyroid hormone (PTH)-producing chief cells of the parathyroid gland, and the cells lining the kidney tubule.  CASR senses small changes in circulating calcium concentration and couples this information to intracellular signaling pathways that activate a phosphatidylinositol-calcium second messenger system and modify PTH secretion or renal cation handling, thus this protein plays an essential role in maintaining mineral ion homeostasis. Mutations in the CASR gene cause familial hypocalciuric hypercalcemia, familial, isolated hypoparathyroidism, and neonatal severe primary hyperparathyroidism.
