Computational Analyses of Protein Structure and Immunogen Design
(2018-08-20)
The sequence of a polypeptide chain determines its structure which in turns determines its function. A protein is stabilized by multiple forces; hydrophobic interaction, electrostatic interactions and hydrogen bond formation ...
Synergistic Influence of Gene Architecture and Promoter Structure on Transcription in Plants : An in silico Analysis
Understanding the structural organisation of genome and insightful information of gene has helped in exploring the regulation and expression of the gene at a molecular and cellular level. In eukaryotes, the gene regulation ...
Substrate Specificity Determinants of Class III Nucleotide Cyclases
(2018-07-31)
Cyclic AMP and cyclic GMP (cAMP and cGMP) are important second messengers in key signal-transduction pathways that mediate various physiological functions in bacteria and eukaryotes. Adenylyl Cyclases (ACs) and Guanylyl ...
The Role of DNA Structural Features of Eukaryotic Promoter Sequences in Transcription Regulation
(2018-09-04)
Understanding the molecular structure of DNA was considered as greatest achievement in modern biology. It helped in understanding fundamental cellular processes such as replication of DNA, nature of the ...
Structure- Function Studies on Triosephosphate Isomerase : Some Old Questions, Some New Insights
This thesis describes biophysical, kinetic, structural, and sequence conservation analysis of the glycolytic enzyme triosephosphate isomerase (TIM). TIM catalyses the diffusion limited isomerization of D-glyceraldehyde-3-phospahte ...
HIV-1 Immunogen Design : Envelope Protein Minimization, Stabilization and Glycan Removal
Effective vaccines exist for a number of viral diseases. However, despite much effort, there is no successful vaccine against the Human Immunodeficiency Virus (HIV-1). The envelope glycoprotein (Env) of HIV-1 gp120, the ...
(p)ppGpp and c-di-GMP : A Tale of Two Second Messengers in Mycobacterium smegmatis
Nucleotide based second messengers are known to regulate wide variety of processes in all domains of life. Two such bacterial second messengers are (p)ppGpp (guanosine tetra- or pentaphosphate) and c-di-GMP (cyclic dimeric ...
Theta-band Spectral Selectivity and Gamma-range Coincidence Detection in Spike Initiation Dynamics of Hippocampal Pyramidal Neurons
In the pursuit to understand information processing in the brain, a general question that is often posed is: What is the neuron encoding? This is addressed by assessing feature selectivity in sensory neurons, which informs ...
Rational Elicitation of Cold Sensitive Phenotypes
Conditional gene expression and conditional mutants provide a means to modulate the expression of specific genes and to control the activity of their protein products in vivo, so as to be able to study their effects on the ...
G-Protein Coupled Estrogen Receptor (hGPER)- Mediated Action of 17β-Estradiol on hTREK-1 Potassium Channel
TREK-1 is a two-pore domain potassium channel that contributes to maintenance of the resting membrane potential of a cell. TREK-1 is involved in several physiological and pathophysiological conditions like nociception, ...
