Research Focus

Research activities: structural intricacies of disease linked intrinsically disordered proteins (IDPs) such as amyloid beta (Aβ), α-synuclein. Understanding membrane less organelles and phase transition. Application of biological Raman spectroscopy FTIR, NMR, AFM EM and fluorescence spectroscopy and molecular dynamics simulations to understand the aggregation and phase transition of protein solution

Research Interest

The lack of a rigid and folded stable structure in IDPs (intrinsically disorder proteins) may provide large plasticity to interact them efficiently with different targets, and thus conformational flexibility aids good efficacy in cell cycle regulation, membrane transport, and different molecular recognition processes. In addition the inherited structural disorder and the hydrophobic patches in it play an important role in formation of membrane less organelles and the production of amyloid like aggregates that is implicated in several human neurological disorders. In our laboratory we attempt to define the role of protein disorder region in formation of membrane less organelles, amyloid aggregates and their implication in Alzheimer’s (AD) and Parkinson disease (PD). To address the role of protein aggregates in AD and PD we are now studying different type of protein oligomers under Raman microscope. In addition, we are involved deeply in developing methods (including multivariate analysis of Raman data) that could aid in the early detection of AD and PD based on Raman signature. We are also studying the formation and possible structure of membrane less organelles which are unique as cellular storage for hormones and neurotransmitters. Raman spectroscopy allows us to obtain very high quality Raman spectrum of protein crystals. We probe the hydration and dynamics of the disordered region and side chain residues in some of the globular proteins in their crystalline form. In addition our laboratory is also engaged in understanding the interaction pattern of IDPs and structured proteins with metal nano-composites. Our results established that porphyrin based inorganic nanoparticles induced helicity in α-synuclein and significantly reduced its fibrillation. Porphyrin-gold made nano-cargo also reduces the dose of doxorubicin and thereby showed improved efficacy towards killing of brain cancer cells. 

Associated research interest is to target allosteric site (that include protein disorder region) of enzymes with small natural and synthetic molecules to modulates their activity, function and overall molecular mechanics. The allosteric modulators can fine-tune protein mechanics. Besides, allosteric sites are evolutionarily less conserved/more diverse even in very similarly related proteins, thus, provides high degree of specificity in targeting a particular protein. Therefore, targeting of allosteric sites is gaining attention as an emerging strategy in rational drug design. However, the experimental approaches provide a limited degree of characterization of new allosteric sites. Computational approaches are useful to analyze and select potential allosteric sites for drug discovery. We use molecular docking, which has become an integral part of the drug discovery process, to predict the  drug- ability of novel allosteric sites as well as the active site on target proteins (e.g Dengue and COVID main proteases) by ligand screening and subsequent analysis by Raman microscopy.
