Research:

Cellular protein quality control (PQC) maintains protein homeostasis at physiological or stress condition. Efficient clearance of misfolded proteins by refolding, degradation or sequestration is critical for cell survival. Molecular chaperones are integral part of PQC. Chaperones help in folding of several proteins linked with cell signaling and gene expression. Thus, chaperones become a potential target for various diseases including cancer, diabetes and even late-onset neurological diseases when efficiency of quality control decreases. However, quality control of such important chaperone clients such as protein kinases or misfolded proteins those are toxic for the cell is still elusive. Using both yeast and mammalian system I am trying to understand the mechanism of cellular protein quality control.
