The extracellular calcium-sensing receptor (CaSR) is a G protein-coupled receptor that has a key role in Ca2+homeostasis via its role in the parathyroid glands and kidneys. New evidence has shown that CaSR also regulates skeletal homeostasis. In this Review, David Goltzman and Geoffrey Hendy discuss the role of CaSR in chondrocytes and development of the cartilagenous growth plate, in osteoblasts and osteoclasts, and effects of CaSR on skeletal development and bone turnover.
