Research Themes
Substrate recognition mechanism of Hsp70 chaperone system
It has been thought that a polypeptide spontaneously folds into its functional state according to the primary amino acid sequence. However, most newly synthesized polypeptides require a set of molecular chaperones to fold their native conformations. Because cytosol is highly crowded with macromolecules, a newly synthesized polypeptide could improperly interact with them and fail to fold. Molecular chaperones protects newly synthesized polypeptides from improper interactions or aggregation, and assist them in maturing into proteins. Although Hsp70 is the major chaperone and has been studied for long time, its substrate-recognition mechanism is not perfectly understood. I have studied Hsp70 using techniques of molecular biology and biochemistry.
