项目摘要
To gain insight into structure-function relationship of Kv channel and other physiological issues, molecular dynamics(MD) simulations were conducted. Atomistic details regarding Kv channel closing mechanism were revealed. We also applied coarse-grained MD simulations to curved membranes, in particular, hemifusion-mimicking membrane systems. The latter analysis showed that lipids with a high degree of negative spontaneous curvature tend to be enriched at the junction of the bilayers that is highly curved. We also showed that cholesterol-dependent formation of lipid microdomains proceeds under strong influence of membrane curvature. The possibility that such curvature dependent localization of microdomains may contribute to the intracellular lipid sorting was discussed.
为了深入了解KV通道和其他生理问题的结构功能关系,进行了分子动力学(MD)模拟。有关KV通道关闭机制的原子细节。我们还将粗粒度MD模拟应用于弯曲的膜,尤其是模拟半缩合的膜系统。后一个分析表明,高度自发曲率的脂质往往会在高度弯曲的双层的连接处富集。我们还表明,在膜曲率的强大影响下,脂质微区域的胆固醇依赖性形成进行。讨论了这种曲率依赖性微区域的定位可能有助于细胞内脂质分选的可能性。
