Technical Data
Parathyroid hormone receptor 1 (PTH/PTHr receptor, PTH1 R)
PTH1 R (Parathyroid hormone receptor 1; also PTH/PTHr receptor) is a predicted 66-68kD member of the G-protein coupled receptor family 2. It is expressed on a variety of cell types, including hepatocytes, renal epithelium, smooth muscle cells, and osteoblasts plus chondrocytes. PTH1 R is a receptor for both PTH and PTHrP, and PTH binding promotes Ca ++ -release from bone, mediated by osteoclast formation. Mature human PTH1 R is a 7-transmembrane glycoprotein 567 amino acids (aa) in length. It contains a long, ligand-binding N-terminal extracellular region (aa 27-188) and a 130 aa cytoplasmic C-terminal domain. Single aa changes such as Gly121Glu, Ala122Thr and Arg255His can impair PTH1 R signaling.

Suitable for use in ELISA, Western Blot and Immunohistochemistry. Other applications not tested.
