Research Areas:

  1. Structural and Functional Characterization of globular proteins and Intrinsically Disordered proteins (IDPs) in presence of Osmolytes/Chemical Chaperones: Focusses on understanding the structural and functional characterization of antioxidant protein systems (Catalase, Superoxide dismutase etc), an important class of enzymes associated with major diseases conditions, and Intrinsically Disordered prtoeins (casein, crystalline etc.) by osmolytes. Elucidating the influence of osmolytes on the two different protein classes may enable us to design solution conditions that may enhance binding of drug targets to these clinically important enzymes. The main motivation is towards technology development for stabilization of Therapeutic/clinically important proteins.
  2. Protein Misfolding/Aggregation/Amyloid formation: Role of chemical chaperones in modulating/regulating the aggregation/amyloid formation of both natively folded and natively unfolded (Intrinsically Disordered Proteins) and understanding their mechanism of action. Identification of the nature of interactions of chemical chaperones with fibrillates/aggregates at different steps of aggregation is a key step towards the discovery and synthesis of target oriented potential inhibitors of these associations.
  3. Medicinal Plant proteomics: Involves the purification and characterization of some novel biologically active proteins from some important medicinal plants like Ashwagandha.  We had already isolated a novel protein from Ashwagandha with anti-cancerous activity, for which we are carrying its further structural and functional characterization. For achieving this goal, our lab is in active collaborations with IIIM, Jammu; ACBR, University of Delhi and CCMB, Hyderabad. The main focus of this research area is towards Development of a Protein drug.
