Mouse Anti-CASR Recombinant Antibody (1315) (CBMAB-1315-CN)

calcium sensing receptor

The protein encoded by this gene is a plasma membrane G protein-coupled receptor that senses small changes in circulating calcium concentration.
The protein senses changes in the extracellular concentration of calcium ions and plays a key role in maintaining calcium homeostasis.

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).

Hypocalciuric hypercalcemia, familial 1 (HHC1): A form of hypocalciuric hypercalcemia, a disorder of mineral homeostasis that is transmitted as an autosomal dominant trait with a high degree of penetrance. It is characterized biochemically by lifelong elevation of serum calcium concentrations and is associated with inappropriately low urinary calcium excretion and a normal or mildly elevated circulating parathyroid hormone level. Hypermagnesemia is typically present. Affected individuals are usually asymptomatic and the disorder is considered benign. However, chondrocalcinosis and pancreatitis occur in some adults.
Hyperparathyroidism, neonatal severe (NSHPT): A disorder characterized by severe hypercalcemia, bone demineralization, and failure to thrive usually manifesting in the first 6 months of life. If untreated, NSHPT can be a devastating neurodevelopmental disorder, which in some cases is lethal without parathyroidectomy.
Hypocalcemia, autosomal dominant 1 (HYPOC1): A disorder of mineral homeostasis characterized by blood calcium levels below normal, and low or normal serum parathyroid hormone concentrations. Disease manifestations include mild or asymptomatic hypocalcemia, paresthesias, carpopedal spasm, seizures, hypercalciuria with nephrocalcinosis or kidney stones, and ectopic and basal ganglia calcifications. Few patients manifest hypocalcemia and features of Bartter syndrome, including hypomagnesemia, hypokalemia, metabolic alkalosis, hyperreninemia, and hyperaldosteronemia.
Epilepsy, idiopathic generalized 8 (EIG8): A disorder characterized by recurring generalized seizures in the absence of detectable brain lesions and/or metabolic abnormalities. Seizure types are variable, but include myoclonic seizures, absence seizures, febrile seizures, complex partial seizures, and generalized tonic-clonic seizures.
