Recent advances in biotechnology such as Hi-C, CRISPR/Cas9 and ribosome display have placed nucleoprotein complexes at center stage. Understanding the structural dynamics of these complexes aids in optimizing protocols and interpreting data for these new technologies. The integration of simulation and experiment has helped advance mechanistic understanding of these systems. Coarse-grained simulations, reduced-description models, and explicit solvent molecular dynamics simulations yield useful complementary perspectives on nucleoprotein complex structural dynamics. When combined with Hi-C, cryo-EM, and single molecule measurements, these simulations integrate disparate forms of experimental data into a coherent mechanism.

核蛋白复合物的大规模模拟:核糖体,核小体,染色质,染色体和CRISPR。

生物技术的最新进展,例如Hi-C,CRISPR / Cas9和核糖体展示已将核蛋白复合物置于中心位置。了解这些复合物的结构动力学有助于优化协议并解释这些新技术的数据。仿真和实验的集成有助于提高对这些系统的机械理解。粗粒度模拟,简化描述模型和显式溶剂分子动力学模拟可提供有关核蛋白复合物结构动力学的有用补充观点。当与Hi-C,cryo-EM和单分子测量结合使用时,这些模拟会将不同形式的实验数据整合到一个连贯的机制中。
