Yeast Biology and Protein Biophysics.
Every cell has a network of proteins known as chaperones that are evolved to refold misfolded proteins back to their native state, and if repairing fails target them for degradation. However under various conditions, protein misfolding exceeds the preservative capacity of cells leading to protein aggregation affecting cellular viability. Thus approaches to further modulate action of chaperone machinery could provide common therapeutic targets for various protein misfolding diseases. Our lab employs both yeast genetics and single molecule approaches to understand why cellular machinery that is optimally evolved to maintain protein homeostasis fails to avert accumulation of misfolded proteins as well as proteinaceous masses known as amyloid. Other aspect of our future research would be to understand the dependency of many of the viral pathogens on host chaperones. Many of viral strains require cellular chaperones for replication suggesting these proteins as potential targets against associated viral diseases. Thus one of the future focus of lab is to investigate interplay among various viral proteins and host chaperones.
