| 1 | 钙离子通道蛋白的研究进展显示文摘钙离子是最广泛存在的细胞内信使,调控着几乎所有生命过程。最近的结构生物学研究解析了很多不同种类的钙离子通道在不同开放-关闭状态下的近原子分辨率结构。有关进展揭示了这些通道的分子组成、动态活动、生理功能、调控修饰的分子基础,为阐明钙信号转导和相关疾病的微观机制提供了理论基础. | 范雪新 杨磊 项斌 王世强 | 2016 | 生物化学与生物物理进展2016，43，12： | 14 |
| 2 | Calcium ion as cellular messenger显示文摘The prominent role Ca2+ion plays as a major small biological messenger is fascinating.There are many physiologically important ions,such as Na+,K+,H+,Cl?,Ca2+,Mg2+,Fe3+,and PO43?that participate in cell signaling.Among them,monovalent ions primarily contribute to rapid electrical signaling,while multivalent ions generally act as a co-factor for chemical reactions by associating with the host molecule through electrostatic or covalent interactions.Ca2+plays both roles.Its transmembrane influx supports the plateau phase of cardiac action potential and helps set the speed of pacemaker potential.Inside the cell。 | ZHENG Jie ZENG XuHui WANG ShiQiang | 2015 | Science China(Life Sciences)2015，58，1： | 8 |
| 3 | Regulation of lysosomal ion homeostasis by channels and transporters显示文摘Lysosomes are the major organelles that carry out degradation functions. They integrate and digest materials compartmentalized by endocytosis, phagocytosis or autophagy. In addition to more than 60 hydrolases residing in the lysosomes, there are also ion channels and transporters that mediate the flux or transport of H^+, Ca^(2+), Na^+, K^+, and Cl^- across the lysosomal membranes. Defects in ionic exchange can lead to abnormal lysosome morphology, defective vesicle trafficking, impaired autophagy, and diseases such as neurodegeneration and lysosomal storage disorders. The latter are characterized by incomplete lysosomal digestion and accumulation of toxic materials inside enlarged intracellular vacuoles. In addition to degradation, recent studies have revealed the roles of lysosomes in metabolic pathways through kinases such as mechanistic target of rapamycin(m TOR) and transcriptional regulation through calcium signaling molecules such as transcription factor EB(TFEB) and calcineurin. Owing to the development of new approaches including genetically encoded fluorescence probes and whole endolysosomal patch clamp recording techniques, studies on lysosomal ion channels have made remarkable progress in recent years. In this review, we will focus on the current knowledge of lysosome-resident ion channels and transporters, discuss their roles in maintaining lysosomal function, and evaluate how their dysfunction can result in disease. | Jian Xiong Michael X.Zhu | 2016 | Science China(Life Sciences)2016，59，8： | 7 |
