Rabbit anti-Human CASR Polyclonal Antibody

Uniprot Id

P41180

Target Species

Human

Target Name

CASR

Target Full Name

Extracellular calcium-sensing receptor

Target Function

G-protein-coupled receptor that senses changes in the extracellular concentration of calcium ions and plays a key role in maintaining calcium homeostasis. Senses fluctuations in the circulating calcium concentration and modulates the production of parathyroid hormone (PTH) in parathyroid glands. The activity of this receptor is mediated by a G-protein that activates a phosphatidylinositol-calcium second messenger system. 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.

Target Involvement

Hypocalciuric hypercalcemia, familial 1 (HHC1); Hyperparathyroidism, neonatal severe (NSHPT); Hypocalcemia, autosomal dominant 1 (HYPOC1); Epilepsy, idiopathic generalized 8 (EIG8)

Target Background

The protein encoded by this gene is a plasma membrane G protein-coupled receptor that senses small changes in circulating calcium concentration. The encoded protein couples this information to intracellular signaling pathways that modify parathyroid hormone secretion or renal cation handling, and thus this protein plays an essential role in maintaining mineral ion homeostasis. Mutations in this gene are a cause of familial hypocalciuric hypercalcemia, neonatal severe hyperparathyroidism, and autosomal dominant hypocalcemia.
