项目摘要

DESCRIPTION (provided by applicant): Membrane proteins play an essential role in controlling the movement of material and information in and out of the cell, in determining the flow and use of energy, as well as in triggering the initiation of numerous signaling pathways. To fulfill these roles, conformational and interaction dynamics exert a dominant influence on their functional behavior, for it is the interplay between structure and dynamics what ultimately defines their function. The Midwest Center for Membrane Protein Structural Dynamics (MMPSD) is proposed as a highly interactive, tightly integrated and multidisciplinary effort focused on elucidating the relationship between structure, free energy landscapes, dynamics and function. The MMPSD will be organized around multidisciplinary project teams with investigators from institutions clustered geographically inn [sic] the Midwest to maximize true interactive collaborations and an efficient exchange of ideas. These teams will study major mechanistic questions associated with membrane protein function as it relates to three major areas: energy transduction in signaling (ion channels and receptors) energy interconversion (transporters and pumps) and chemo-transduction pathways (membrane-embedded proteases and phosphatases). Our ultimate goals is to decode the general mechanistic principles that govern protein movement and its associated fluctuation dynamics by dissecting and analyzing the molecular and dynamical bases of these functions at an unprecedented and quantitative level, as well as exploiting this information to engineer altered and novel activities into membrane protein frameworks to rationally evolve new functions. To accomplish its goals, the MMPSD will develop in parallel a set of tools, concepts and reagents to: 1) Determine time-averaged structures of "Archetype" membrane proteins using Chaperone-assisted crystallization methods; 2) Apply state of the art spectroscopic methods (Magnetic Resonance, Fluorescence) to follow conformational changes and dynamics of the determined structures; and 3) Design and implement novel computational approaches to link static and dynamic data with function. Four core facilities will feed and interconnect with the individual projects in a highly interactive way. The cores will support the research in the Center by providing service and expertise in four critical areas: Membrane protein expression, the establishment of chemical synthesis capabilities for probes and detergents, the generation of a large variety of crystallization chaperones and other target binders, and generation of a pipeline of novel membrane targets through metagenomics approaches. All of the information, tools and new reagents/targets will be shared with the research community at large through the "membrane protein dynamics gateway", a state of the art web page and a series of scientific meetings open to the public.

描述（由申请人提供）：膜蛋白在控制物质和信息进出细胞、确定能量的流动和使用以及触发许多信号传导途径的启动方面发挥重要作用。为了实现这些功能，构象和相互作用动力学对它们的功能行为产生了主导影响，因为结构和动力学之间的相互作用最终决定了它们的功能。中西部中心膜蛋白结构动力学（MMPSD）提出作为一个高度互动，紧密结合和多学科的努力，重点是阐明结构，自由能景观，动力学和功能之间的关系。 MMPSD将围绕多学科项目团队组织，来自中西部地理上聚集的机构的调查人员将最大限度地实现真正的互动合作和有效的思想交流。这些团队将研究与膜蛋白功能相关的主要机制问题，因为它涉及三个主要领域：信号传导中的能量转导（离子通道和受体）能量相互转换（转运蛋白和泵）和化学转导途径（膜嵌入的蛋白酶和磷酸酶）。我们的最终目标是解码的一般机械原理，管理蛋白质运动及其相关的波动动力学解剖和分析这些功能的分子和动力学基础在一个前所未有的和定量的水平，以及利用这些信息工程改变和新的活动到膜蛋白框架，合理地发展新的功能。为了实现其目标，MMPSD将同时开发一套工具、概念和试剂，以：1）使用伴侣辅助结晶方法确定“原型”膜蛋白的时间平均结构; 2）应用最先进的光谱方法（磁共振、荧光）跟踪确定结构的构象变化和动力学; 3）设计并实现了新的计算方法，将静态和动态数据与函数联系起来。四个核心设施将以高度互动的方式与各个项目相互连接。核心将通过在四个关键领域提供服务和专业知识来支持中心的研究：膜蛋白表达，建立探针和洗涤剂的化学合成能力，产生各种各样的结晶分子伴侣和其他目标结合剂，以及通过宏基因组学方法产生新的膜靶点。所有的信息，工具和新的试剂/目标将通过“膜蛋白动力学网关”，一个最先进的网页和一系列向公众开放的科学会议与广大研究界分享。
