Cloning of the PTH/PTHrP receptor has established a new class of a receptor family which couples with G-proteins. When this receptor is occupied by PTH or PTHrP, activation of adenylate cyclase and phospholipase C occurs. Site-specific mutagenesis is extensively employed to study the structure-function relationship. The mechanisms whereby PTH/PTHrP receptor level is regulated are also being studied. PTH/PTHrP receptor knock-out and PTHrP knock-out mice show similar skeletal abnormalities but the former apparently die earlier before birth. There are still many problems to be elucidated, such as the reason for the subtle difference of PTH action and PTHrP action, and the role that this receptor plays in the pathogenesis of pseudohypoparathyroidism Ib.

D011485	Protein Binding	The process in which substances, either endogenous or exogenous, bind to proteins, peptides, enzymes, protein precursors, or allied compounds. Specific protein-binding measures are often used as assays in diagnostic assessments.	Plasma Protein Binding Capacity,Binding, Protein
D011547	Pseudohypoparathyroidism	A hereditary syndrome clinically similar to HYPOPARATHYROIDISM. It is characterized by HYPOCALCEMIA; HYPERPHOSPHATEMIA; and associated skeletal development impairment and caused by failure of response to PARATHYROID HORMONE rather than deficiencies. A severe form with resistance to multiple hormones is referred to as Type 1a and is associated with maternal mutant allele of the ALPHA CHAIN OF STIMULATORY G PROTEIN.

D018016	Receptors, Parathyroid Hormone	Cell surface proteins that bind PARATHYROID HORMONE with high affinity and trigger intracellular changes which influence the behavior of cells. Parathyroid hormone receptors on BONE; KIDNEY; and gastrointestinal cells mediate the hormone's role in calcium and phosphate homeostasis.	Parathyroid Hormone Receptors
