项目摘要
DESCRIPTION (provided by applicant): The crowded and compartmentized environments inside cells are very different from the typical dilute conditions of in vitro and in silico biophysical studies of biomacromolecules. The long-term objectives of this project are to address the fundamental questions of how and how much macromolecular crowding and confinement affect thermodynamic and kinetic properties of biomolecules and to quantitatively reconstruct the influences of in vivo environments on these properties. The project has three integral components. Aim 1 is to develop realistic theoretical models for crowding, which provide physical insight and yet allow for incorporation of molecular details. Aim 2 is to carry out simulations and calculations for the interactions of proteins with atomistically detailed crowders, thereby direct quantitative comparison with in vitro experiments can be made. Aim 3 is to validate theoretical predictions by in vitro experiments. Test problems encompass effects of crowding on the thermodynamics and kinetics of protein folding and protein binding. This project will overcome some of the major limitations of current approaches and make significant advances toward quantitatively reconstructing the influences of in vivo environments.
PUBLIC HEALTH RELEVANCE: The proposed research will lead to a deeper understanding of biological processes inside cells and of pathological conditions such as Parkinson's disease in particular. This understanding may form the foundation for more accurate prognoses of and better therapies against such diseases.
描述(由申请人提供):细胞内的拥挤和区室化环境与生物大分子的体外和计算机生物物理研究的典型稀释条件非常不同。该项目的长期目标是解决大分子拥挤和限制如何以及多大程度上影响生物分子的热力学和动力学性质的基本问题,并定量重建体内环境对这些性质的影响。该项目有三个组成部分。目标1是开发现实的理论模型拥挤,提供物理的洞察力,但允许纳入分子的细节。目的2是进行模拟和计算的蛋白质与原子详细的拥挤的相互作用,从而可以在体外实验进行直接的定量比较。目的3是通过体外实验验证理论预测。测试问题包括拥挤对蛋白质折叠和蛋白质结合的热力学和动力学的影响。该项目将克服目前方法的一些主要局限性,并在定量重建体内环境的影响方面取得重大进展。
公共卫生相关性:这项拟议中的研究将有助于更深入地了解细胞内的生物过程,特别是帕金森病等病理状况。这种理解可能为更准确地诊断和更好地治疗这些疾病奠定基础。
