Biology Structure-Based Simulation and Sampling of Transcription Factor Protein Movements along DNA from Atomic-Scale Stepping to Coarse-Grained Diffusion Chao E*1, Liqiang Dai*1,2, Jiaqi Tian3,4, Lin-Tai Da4, Jin Yu5,6,7 1Beijing Computational Science Research Center, 2Shenzhen JL Computational Science and Applied Research Institute, 3School of Medical Informatics and Engineering, Xuzhou Medical University, 4Key Laboratory of Systems Biomedicine (Ministry of Education), Shanghai Center for Systems Biomedicine, Shanghai Jiao Tong University, 5Department of Physics and Astronomy, University of California, Irvine, 6Department of Chemistry, University of California, Irvine, 7NSF-Simons Center for Multiscale Cell Fate Research, University of California, Irvine The goal of this protocol is to reveal structural dynamics of one-dimensional diffusion of protein along DNA, using a plant transcription factor WRKY domain protein as an exemplary system. To do this, both atomistic and coarse-grained molecular dynamics simulations along with extensive computational samplings have been implemented. Chemistry Methionine Functionalized Biocompatible Block Copolymers for Targeted Plasmid DNA Delivery Yang Wu*1, Wei Zhang*2, Jian Zhang2, Zhi-Xiang Mao3, Li Ding2, Hao Li3, Rong Ma1, Jin-Hai Tang2 1Research Center of Clinical Oncology, Jiangsu Cancer Hospital & Jiangsu Institute of Cancer Research & Nanjing Medical University Affiliated Cancer Hospital, 2Department of General Surgery, The First Affiliated Hospital with Nanjing Medical University, 3School of Clinical Medicine, Xuzhou Medical University This work presents the preparation of methionine functionalized biocompatible block copolymers (mBG) via the reversible addition-fragmentation chain transfer (RAFT) method. The plasmid DNA complexing ability of the obtained mBG and their transfection efficiency were also investigated. The RAFT method is very beneficial for polymerizing monomers containing special functional groups.
