FUNCTION: G-protein-coupled receptor that senses changes in the extracellular concentration of calcium ions and plays a key role in maintaining calcium homeostasis (PubMed:7759551, PubMed:8702647, PubMed:8636323, PubMed:8878438, PubMed:17555508, PubMed:19789209, PubMed:21566075, PubMed:22114145, Pub...
FUNCTION: G-protein-coupled receptor that senses changes in the extracellular concentration of calcium ions and plays a key role in maintaining calcium homeostasis (PubMed:7759551, PubMed:8702647, PubMed:8636323, PubMed:8878438, PubMed:17555508, PubMed:19789209, PubMed:21566075, PubMed:22114145, PubMed:23966241, PubMed:25292184, PubMed:25104082, PubMed:26386835, PubMed:25766501, PubMed:22789683). Senses fluctuations in the circulating calcium concentration and modulates the production of parathyroid hormone (PTH) in parathyroid glands (By similarity). The activity of this receptor is mediated by a G-protein that activates a phosphatidylinositol-calcium second messenger system (PubMed:7759551). The G-protein-coupled receptor activity is activated by a co-agonist mechanism: aromatic amino acids, such as Trp or Phe, act concertedly with divalent cations, such as calcium or magnesium, to achieve full receptor activation (PubMed:27434672, PubMed:27386547). {ECO:0000250|UniProtKB:Q9QY96, ECO:0000269|PubMed:17555508, ECO:0000269|PubMed:19789209, ECO:0000269|PubMed:21566075, ECO:0000269|PubMed:22114145, ECO:0000269|PubMed:22789683, ECO:0000269|PubMed:23966241, ECO:0000269|PubMed:25104082, ECO:0000269|PubMed:25292184, ECO:0000269|PubMed:25766501, ECO:0000269|PubMed:26386835, ECO:0000269|PubMed:27386547, ECO:0000269|PubMed:27434672, ECO:0000269|PubMed:7759551, ECO:0000269|PubMed:8636323, ECO:0000269|PubMed:8702647, ECO:0000269|PubMed:8878438}.
