Research Interests:

My current research is focusing on endoplasmic reticulum-associated degradation (ERAD). ERAD is a mean for protein quality control of the secretory pathway and for regulating certain normal protein levels. It involves coordinated events of protein dislocation from the ER, ubiquitination and degradation by the proteasome. My major work is to understand how the substrate proteins are transported from the ER to the cytosol. In my previous research, I have identified a protein that was well known as a nuclear import factor, importin β, as a protein involved in ERAD. It may co-work with a previously reported protein complex, VCP complex, and help the aberrant folded proteins to pass through the membrane. And we recently established a dislocation-dependent reconstitute GFP (drGFP) assay that can be used to measure the protein dislocation in the cell.
