Research Summary

With more than 60% marketed drugs targeting membrane proteins, a detailed understanding of structural and functional regulation of membrane protein is of pivotal interest. Recently, we have made remarkable progress towards obtaining structures of independent membrane proteins. Nevertheless, in the crowded milieu of the membrane, membrane proteins form a large number of dynamic and transient complexes with other soluble and membrane proteins, lipids and various other endogenous and extraneous regulators, which in turn govern cellular physiology. Hence, discovering these complexes and deconvoluting their spatiotemporal evolution along the progression of cellular cycle pose the next big challenge.  Using native mass spectrometry in combination with other experimental and theoretical approaches, the lab provides a novel top down deconstructive vantage point to this problem. Our approach enables us to detect membrane protein complexes directly from the native environment, identify the novel interacting partners, and subsequently track their spatiotemporal progression. Applying these to dynamic macro-molecular membrane associated system our aim is to delineate the molecular mechanisms behind various cellular signalling pathways. 

We work closely with researchers with varied expertise. While we love the physicists and the chemists who develop novel experimental tools, we cannot live without the biologists and the medics who use these cutting-edge techniques to solve the problems most pertinent to humankind. We even have an anthropologist. We are always interested in innovators, the creative thinkers, the dreamers, and the doers.
