Research Abstract

Chaperonins are a group of molecular chaperone that assists in protein folding in the cell. In this project, we analyzed two eukaryotic chaperonins: cytosolic chaperonin CCT and mitochondrial chaperonin HSP60. In the study of CCT, we found that CCT possesses GTPase activity in addition to the ATPase activity. In the study of HSP60, we found that football-like complex plays an important role in the function of HSP60 after formation of the football-like complex from single-ring complex via double-ring complex. These results contain important findings to understand chaperonin functions.
