细胞膜表面受体一直是一个针对有机大分子的概念。近来许多研究表明在多种细胞表面存在钙受体(CaR),并发现此类受体不但在细胞外游离钙离子浓度的调节中起重要作用,而且与许多生理病理现象密切相关。本文简要介绍其概念、分布、结构功能以及生理病理。 Cell membrane surface receptors have always been a concept for organic macromolecules. Recently, many studies show that there are calcium receptors (CaRs) on various cell surfaces and found that these receptors not only play an important role in the regulation of extracellular free calcium concentration, but also are closely related to many physiological and pathological phenomena. This article gives a brief introduction to its concept, distribution, structural function, and physiology and pathology.
