  • Professor Haifeng Chen, PhD Supervisor. Editor member of JCIM. He got the bachelor, master, PhD degree from Xi’an Jiao Tong University, Sichuan University, and University of Paris 7, France. He did postdoc research at University of California, Irvine. His research is focused on precise force field for IDPs and de novo protein design.

Research Interests

Precise force field research for intrinsically disordered proteins

Intrinsically disordered proteins (IDPs) or intrinsically disordered regions have not fixed tertiary structure, but play key roles in signal regulation, molecule recognition, and drug target. However it is difficult to study the structure and function of IDPs by traditional experimental methods because of their diverse conformations. Limitations of current generic protein force fields were reported in the previous simulations of IDPs. We have also explored to overcome these limitations by developing precise force fields ff99IDPS and ff14IDPS to correct the dihedral distribution for eight disordered promoting residues, ff14IDPSFF, CHARMM36IDPSFF, OPLSIDPSFF, ff03CMAP force fields for all 20 naturally occurring amino acids, and ESFF1 force field for environmental specific residues to further improve the quality in the modeling of IDPs. Extensive tests of IDPs and unstructured short peptides show that the simulated Cα chemical shifts with the precise force field are in quantitative agreement with those from NMR experiment and are more accurate than the base generic force field. Furthermore, the simulation effectiveness is also higher than other force fields. These findings confirm that the newly developed precise force field can improve the conformer sampling of intrinsically disordered proteins.

Computer Aided Innovation Drug Development

Computer-aided drug design uses computational approaches to discover, develop, and analyze drugs and similar biologically active molecules.  In our group, we used three dimension quantitative structure and activity relationship (3D-QSAR) combined with molecular docking, molecular dynamics simulation to research the molecular mechanism for HIV-1 protease, integrase, reverse Transcriptase, CCR5, respiratory syncytial virus fusion protein, and tumor, etc.
