What we do

Understanding how proteins accurately fold into three-dimensional structures in the cell is a central problem in modern biology. After ribosomal synthesis, the nascent polypeptides must actively fold into their native conformations to function properly within the cell. Protein misfolding leads to cellular accumulation of incorrectly folded proteins, which is the cause of many diseases including Alzheimer's, Huntington, Prion diseases, and Cancer. Ordered protein folding in the cellular cramped chaos is only possible under the supervision of specialized proteins, collectively referred as "Molecular Chaperones" which belong to Hsp70 and Hsp40/J-class. These highly conserved group of proteins recognize and stabilize partially folded intermediates of proteins during cellular processes such as protein translation, transport across organellar membranes, folding and degradation, as well as facilitating the refolding of proteins damaged after exposure of cells to stress.

The long-term goal of our research is to understand the intricate functional network of Hsp70 and Hsp40/J-class in the cytosol and different cell organelles. By utilizing yeast and mammalian model systems, my lab will investigate the cellular functions of molecular chaperones using a combination of experimental tools from genetics and cell biology with biochemistry and biophysics. We will address the role(s) of molecular chaperones in following different physiological functions.
