  • Product Description

    Parathyroid hormone (PTH) plays a critical role in mineral ion homeostasis, particularly in bone and kidney (Mannstadt et al., 1999; Gensure et al., 2005). A related peptide, parathyroid hormone-related peptide (PTHrP), plays an important role in skeletal development. Both peptides exert their biological actions by binding to a class B GPCR, PTH1R, that signals primarily by activation of adenylate cyclase (Schipani et al., 1993). Mutations in PTH1R have been identified as the cause of Jansen's metaphyseal chondrodysplasia, Blomstrand's chondrodysplasia, and enchondromatosis (Schipani and Provot, 2003). Intermittant treatment with PTH has important clinical utility in building bone mass in patients with osteoporosis (Rosen, 2003). Cloned human PTH1R- membrane preparation is an ideal tool for screening for interactions between PTH1R and its ligands.
