项目摘要
This subproject is one of many research subprojects utilizing the resources
provided by a Center grant funded by NIH/NCRR. Primary support for the subproject
and the subproject's principal investigator may have been provided by other sources,
including other NIH sources. The Total Cost listed for the subproject likely
represents the estimated amount of Center infrastructure utilized by the subproject,
not direct funding provided by the NCRR grant to the subproject or subproject staff.
In the rhodopsin family of G-Protein Coupled Receptors (GPCRs), absorption of light and isomerization of the retinal chromophore from the 11-cis (inverse agonist) to the all-trans (agonist) geometry triggers a sequence of protein conformational changes ultimately leading to the formation of the pre-activated Meta-1 state on the microsecond timescale, followed by the activated Meta-2 state on the millisecond timescale. To begin to understand the conformational changes that characterize the activation of the squid rhodopsin GPCR, we propose microsecond timescale molecular dynamics (MD) simulations of squid rhodopsin in a hydrated lipid bilayer consisting of 1-stearoyl-2-docosahexaenoyl- sn-glycero-3-phosphocholine (SDPC) lipid molecules.

在G蛋白偶联受体(GPCR)的视紫红质家族中,光的吸收和视网膜发色团从11-顺式(反向激动剂)到全反式(激动剂)几何结构的异构化触发了一系列蛋白质构象变化,最终导致在微秒时间尺度上形成预活化的Meta-1状态,随后在毫秒时间尺度上形成活化的Meta-2状态。为了开始了解鱿鱼视紫红质GPCR激活的构象变化特征,我们提出了微秒时间尺度的分子动力学(MD)模拟鱿鱼视紫红质在由1-硬脂酰-2-二十二碳六烯酰-sn-甘油-3-磷酸胆碱(SDPC)脂质分子组成的水合脂质双层。
