Abstract: To explore protein complex structures and interactions, a protein docking method was proposed, and the prediction and scoring evaluations of CAPRI from 2014 were conducted. Firstly, the structure modeling method was carried out to predict the protein monomer structure, and Fast Fourier Transformation (FFT) was applied to perform the global conformational searching. Then, the protein complex conformations were refined and evaluated by all-atom statistical potential function. The summarized results from Rounds 32-37 of CAPRI show that this docking method predicts the near-native structures with L_RMSD < 2.0×10^-10 m in the experiments of T104, T105, T111 and T118. Compared with other international excellent groups, the advantage and disadvantages in the prediction and scoring experiments were analyzed. Finally, the possible improvements for protein structure prediction in the oncoming experiments were proposed.
