Analysis of functions of molecular chaperones and its applications

 

Molecular chaperones are ubiquitous proteins that assist folding, assembly, transport and degradation of proteins within the cell. Our group are interested in the molecular mechanism of prefoldin, one of molecular chaperone, which assists a protein folding by capturing folding intermediate and transferring it to chaperonin. We are also interested in the application of molecular chaperone in Biotechnology field. Various research using these multidisciplinary approaches are carried out mainly with biochemical and biophysical experimental techniques including single molecule imaging.
