Involvement in Projects

Computational biophysical study of human shaker-type ion channels: Here, I have tried to correlate the

structure-function relationship among Kv1.1, Kv1.3 & Kv1.5 ion channel as well as addressed some of the

major existing questions related to their voltage dependent behavior such as functional diversity within ion

channel families, their gating mechanism & ion conduction, role of some particular disease causing mutations,

interaction, and inhibition of the channel by small polypeptides or other compounds.

Genomic analysis of Plasmodium falciparum: Using subtractive genomic approach and computational

genomic approaches, I have identified some new drug targets in Plasmodium falciparum which are responsible

for the survival of the parasite. Additionally, we have characterized its LytB protein and tried to find some

novel lead molecule with potential anti-malarial properties.

Studying structure-function relationship of cystatin super families of proteins: In this project, we

have studied the mechanism of all atom based interaction of several cystatins with cysteine proteases like

cathepsins and papains.

Studying the role of tea catechins/ curcumin in pulmonary artery smooth muscle cells: Inhibition of

PLD activity was studied by means of interaction with cytohesin1-Arf6GDP and tea catechins/ curcumin,

which has importance in prevention of several diseases such as pulmonary hypertension, cancer and

neurodegenerative diseases.

Activation/inhibition of SIRT1 by some newly synthesized 1,4-dihydropyridine molecules: In this

project, we are investigating the regulation of apoptosis by activation/ inactivation of SIRT1 in several cancer

cells using a series of newly synthesized 1,4-dihydropyridine molecules.

Characterization of circular RNAs in different human cancer lines: Here, we study the differential

expression of non-coding circular RNAs in different human cancer lines which can be further used as suitable

biomarkers.

Database on enzyme Dehydrogenage: Actively participated in developing the database on enzyme

dehydrogenage (http://www.bifku.in/DBD/).
