| Research Abstract |
G-Protein coupled receptors (GPCRs) are one of the most important drug target proteins today. However, the 3D structures of GPCRs have not yet been determined by X-ray crystallography, except a few proteins, because GPCRs are difficult to crystallize. In addition, due to the huge structural fluctuation of GPCRs, there is a limitation to computationally predict GPCR's accurate conformation.
This study developed a new method for modeling GPCR thermal fluctuations, where conformation changes of the proteins are modeled by combining fluctuations on multiple time scales. This study proposed a novel method which predicts a best 3D structure of a GPCR from a variety of fluctuating candidate structures, by using the evolutionary computation including receptor-ligand docking simulations. The method was validated using human leukotriene B4 receptor BLT1 as a sample GPCR.
