这个基因编码的蛋白质是一种质膜G蛋白偶联受体，能感觉到循环钙浓度的微小变化。编码的蛋白质将这些信息与细胞内的信号传导途径结合起来，这些信号传导途径可以调节甲状旁腺激素的分泌或肾离子的处理，因此这种蛋白质在维持矿物离子的稳态中起着至关重要的作用该基因突变是家族性低钙血症、新生儿重度甲状旁腺功能亢进和常染色体显性遗传性低钙血症的原因。[由RefSeq提供，2017年8月]
The protein encoded by this gene is a plasma membrane G protein-coupled receptor that senses small changes in circulating calcium concentration. The encoded protein couples this information to intracellular signaling pathways that modify parathyroid hormone secretion or renal cation handling, and thus this protein plays an essential role in maintaining mineral ion homeostasis. Mutations in this gene are a cause of familial hypocalciuric hypercalcemia, neonatal severe hyperparathyroidism, and autosomal dominant hypocalcemia. [provided by RefSeq, Aug 2017]
