Structural and Functional Investigation of a Multi-drug Efflux Transporter QacA
The emergence of multi-drug resistance in bacteria is a global health care challenge. One of the effective means of gaining antimicrobial resistance, among superbugs, is through expression of efflux pumps. Quaternary ...
Suppression of epileptiform activity by lactate through HCA1 and GIRK channel activation in rat subicular pyramidal neurons
In the present study, we report a lactate-induced hyperpolarization and reduction of epileptiform activity in subicular weak burst firing and regular firing neurons using patch clamp electrophysiology. We showed the ...
Structural and functional studies on a small Heat Shock Protein from Entamoeba histolytica
Small Heat Shock Proteins (sHSPs) are molecular chaperones that bind to unfolding proteins during cellular stress to prevent them from aggregation. Once the normal conditions are restored, sHSPs release the bound substrate ...
Stimulus statistics and HCN current mediated resonance sets the scale of input-output mapping in Stellate cells of the Medial Entorhinal Cortex
The functional significance of the computations performed by Stellate cells of the Medial
Entorhinal Cortex, proven time and again, makes them insightful, yet intriguing. The
gradients of the intrinsic properties of these ...
Structure Function Studies Of Biologically Important Simple Repetitive DNA Sequences
(Indian Institute of Science, 2007-03-09)
The recent explosion of DNA sequence information has provided compelling evidence for the following facts. (1) Simple repetitive sequences-microsatellites and minisatellites occur commonly in the human genome and (2) these ...
First thorough characterization of the structure, interactions and specificity of an archeal lectin with implication for TB infection
Decades long studies on plant lectins carried out in this laboratory have contributed substantially to glycobiology and helped in the initiation and development of macromolecular crystallography in India. Subsequently the ...
Solution structures and interaction studies of mycobacterial MazEF6 toxin-antitoxin system
Toxin-Antitoxin (TA) systems are stress response systems found on plasmids and chromosomes
of bacteria and archaea. They are involved in important functions such as
plasmid maintenance, programmed cell death, persister ...
Structural and Functional Analysis of Proteins involved in Microbial Stress Tolerance and Virulence
(2018-08-11)
The genus Salmonella consists of pathogenic gram negative organisms which infect intestines of birds, animals and humans. They are the causative agents of salmonellosis which is characterised by diarrhoea, nausea, fever ...
