The Ca2+-sensing receptor(the Ca SR),a G-protein-coupled receptor,regulates Ca2+ homeostasis in the body by monitoring extracellular levels of Ca2+([Ca2+]o) and responding to a diverse array of stimuli.Mutations in the Ca2+-sensing receptor result in hypercalcemic or hypocalcemic disorders,such as familial hypocalciuric hypercalcemia,neonatal severe primary hyperparathyroidism,and autosomal dominant hypocalcemic hypercalciuria.Compelling evidence suggests that the Ca SR plays multiple roles extending well beyond not only regulating the level of extracellular Ca2+ in the human body,but also controlling a diverse range of biological processes.In this review,we focus on the structural biology of the Ca SR,the ligand interaction sites as well as their relevance to the disease associated mutations.This systematic summary will provide a comprehensive exploration of how the Ca SR integrates extracellular Ca2+ into intracellular Ca2+ signaling. 展开更多
