离子是细胞内信息传递的重要信使。很早以前,人们就注意到钙离子在细胞内具有多方面功能,例如细胞收缩,细胞跨膜运输,神经递质释放,DNA的合成、细胞分裂以及细胞运动等生理过程中都与钙离子有关。但关于钙离子作用的分子机制如何,尚不了解。直到六十年代以来,人们发现了一系列可与钙离子结合的蛋白质,才逐步揭开了钙离子的生物学活性之迷。在钙结合蛋白的家族中,最引人
Ions are important messengers of intracellular information transmission. A long time ago, people noticed that calcium ions have many functions in cells, such as cell contraction, cell transmembrane transport, neurotransmitter release, DNA synthesis, cell division, and cell movement. . However, the molecular mechanism of calcium ion is still unknown. Until the 1960s, people discovered a series of proteins that could bind to calcium ions, gradually opening the door to the biological activity of calcium ions. Among the family of calcium binding proteins, the most attractive
