Structural biology of soluble and transmembrane proteins, and De novo design of proteins.

Proteins are workhorses of a cell, engaged in a wide range of tasks comprising structural stability, cell signaling, catalysis, transporting, molecular printing, membrane fusion, regulation, etc. Understanding the mechanism that underlies the functioning of these molecular gadgets is an intriguing question, and defines the fundamentals of biological processes. This is an interdisciplinary research program as we set out to address the question using X-ray crystallographic methods coupled with biophysical, biochemical and computational approaches.

Our structural biology group aim to deduce the structure based mechanism for the functioning of cation selective channels from viruses. The structures not only enhance our current knowledge, but also provide leading point for the structure based drug design. Also, we are interested in the structural biology of bacterial two component systems, a wide spread signal transducers.

Our other research program is de novo protein design, which aim to put our understanding of principles that define protein folding and functioning into test. Here, we seek to design scaffolds that are tailored to have predetermined non-covalent interactions as well as functions.
