Cholinergic-receptor-independent modulation of intrinsic properties of subicular neurons through inhibition of hyperpolarization-activated cyclic nucleotide-gated channels
Acetylcholine release is vital in tuning the hippocampal theta oscillations. Subiculum, the output
region of the hippocampus endowed with different neuronal subtypes, also generates theta oscillations
during arousal and ...
Stereochemical studies on peptide and protein structures: Implications for validation, flexibility, and dynamics
Accuracy of 3-D structures of proteins is crucial, both in terms of its agreement with the experimental data used to determine the structure and stereochemistry, especially when they are utilized for applications like drug ...
CcdB : Stability, folding and application to design novel antibacterials
The primary amino acid sequence typically dictates the ultimate conformation of the protein. Mutations in the sequence demonstrate neutral, positive or negative effects on the structure-function relationship of the protein. ...
Structural and DNA binding properties of ARID domains present in hSWI/SNF chromatin remodeling complex subunits
The SWI/SNF complexes are multisubunit-containing protein complexes that are involved in chromatin-remodeling processes in the eukaryotic cells. In higher eukaryotes, SWI/SNF complexes contain one or more mutually exclusive ...
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 ...
Use of sub-family specific residues of protein modules in recognizing sites of functional and structural specialization
Functional and regulatory features of a protein in a living system are determined by several factors
such as chemical nature and three-dimensional arrangement of residues in the functional site, spatial
and temporal ...
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 ...
Solution structures and conformational isomerism of novel conopeptides from Indian marine cone snails
This thesis describes the structure determination of peptides found in marine cone snails’
venom at atomic resolution and their biological activity. Chapter 1 gives a brief introduction
to the cone snails, conopeptides, ...
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 ...
Single-channel studies on human TREK-1 (hTREK-1) channels to intracellular ischemia related factors
TREK-1, a member of the two-pore domain family of potassium channels, majorly contributes
to the maintenance of resting membrane potential of a cell and has been reported to respond to
ischemic levels of intracellular ...
