PA1-934A detects calcium sensing receptor (CaSR) from human and rat tissues.
PA1-934A has been successfully used in Western blot and ICC/IF procedures. By Western blot, this antibody detects an ~120 kDa protein representing CaSR from HEK393 cells and rat brain homogenate.
The PA1-934A immunizing peptide corresponds to amino acid residues 12-27 from rat CaSR. This peptide (Cat.# PEP-009) is available for use in neutralization and control experiments.
The calcium sensing receptor (CaSR) has been shown to play a major role in regulating parathyroid hormone secretion and subsequently influencing the calcium concentration of extracellular fluids. Based on sequence analysis of cDNA clones it appears that the CaSR is similar to the 7-transmembrane-domain G-protein-coupled receptor superfamily. Changes in extracellular calcium are thought to modulate a balance between proliferation and differentiation in a variety of cell types. In normal primary keratinocytes and breast epithelial cells, proliferation is inhibited and elevated extracellular calcium levels trigger differentiation. Malignant transformations of these cell types are accompanied by a loss of responsiveness to the anti-proliferative effects of elevated extracellular calcium. Several disorders of calcium homeostasis have been linked to mutations in the CaSR. These include familial hypocalciuric hypercalcemia (FHH), neonatal severe hyperparathyroidism (NSHPT), and autosomal dominant hypocalemia (ADHypo).
