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, ... -
GABAA Receptor Mediated Phasic and Tonic Inhibition in Subicular Pyramidal Neurons
(2018-07-28)GABA is the major inhibitory neurotransmitter in the central nervous system. It binds to two types of receptors –ionotropic GABAA and metabotropic GABAB. The GABAA receptor directly gates a Clionophore that causes ... -
Garlic (Allium Sativum) Agglutinin I: Specificity, Binding And Folding Mechanism
(Indian Institute of Science, 2006-11-08)Lectins are a class of proteins that bind to carbohydrates with a high degree of specificity. They are involved in various cellular processes such as, host - pathogen interactions, targeting of proteins within cells, cell ... -
Genome-Wide And Structural Analyses Of Protein Kinase Superfamily
(2010-04-12)A signal transduction process refers to chain of highly regulated biochemical steps which results in the transfer of signal in response to a stimulus in the extracellular environment to the intracellular compartments such ... -
gp120 Immunogen Design And Characterization
(2011-10-21)HIV-1 is the causative agent for AIDS and has been a major focus of research for the past two decades. Though there is a combination therapy in place known as the “Highly Active Anti-Retroviral Therapy” (HAART), its ... -
HIV-1 and SARS-CoV-2 immunogen design
Human Immunodeficiency Virus (HIV-1) is the aetiologic agent of AIDS. Presently there are ~38 million HIV-1 infected individuals worldwide and ~1 million deaths in 2019. Since its discovery, the quest for vaccine candidate ... -
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 ... -
Homeostasis of cyclic-di-AMP in Mycobacterium smegmatis: Functional and structural contributions of c-di-AMP synthase (MsDisA) and hydrolase (MsPDE)
In bacteria, cyclic-di-nucleotide based second messengers regulate various physiological processes including the stress response. For the past decades, cyclic diadenosine monophosphate (c-di-AMP) has emerged as a crucial ... -
Identification, characterization, structure, and assembly of type III toxin-antitoxin systems from Escherichia coli
Bacteria adopt several defense strategies to enable their survival against the environmental threats they encounter from time to time. Toxin-antitoxin (TA) systems are being understood as a key bacterial defense mechanism ... -
In Silico Perspectives on RNA Structures Modulating Viral Gene Expression and Mechanics of tRNA Transport
(2018-07-19)The repertoire of cellular functions mediated by Ribonucleic acid (RNA) molecules have expanded considerably during the last two decades. The role played by RNA in controlling and regulating gene expression in ... -
Influence of the substrate specificity of Mycobacterium tuberculosis ClpX on the transcriptional profile
Cellular homeostasis in bacteria is maintained by diverse molecular machines. These include several one-component systems (OCS), two- component systems (TCS), chaperone proteins, proteases, proteolytic complexes and ... -
Insights into the conformational stability & pharmacology of peptides through side chain and backbone modification
The first part of the work presented in the thesis deals with CH-pi interaction, which is a lesser-known non-covalent interaction in proteins. We identified several CH-pi donor-acceptor pairs involving amino acids side ... -
Insights Into The Mechanistic Details Of The M.Tuberculosis Pantothenate Kinase : The Key Regulatory Enzyme Of CoA Biosynthesis
(2013-04-26)Tuberculosis (TB), caused by Mycobacterium tuberculosis, has long been the scourge of humanity, claiming millions of lives. It is the most devastating infectious disease of the world in terms of mortality as well as morbidity ... -
Integration of sequences, structures, dynamics to study functional divergence in homologous proteins and their assemblies
Functions of proteins are governed by their sequences, structures, dynamics and assembly. Modulation of these factors during evolution renders functional divergence in related proteins that have originated from the common ... -
Integrative modeling of NS3 helicase function with molecular kinetics, molecular simulations and machine learning
The viral NS3 helicase is a crucial enzyme involved in the RNA replication of positive strand ssRNA viruses of the Flaviviridae family. The NS3 is an active motor that binds RNA and couples ATP hydrolysis to the mechanical ... -
Interaction Of Chaperone SecB With Protein Substrates: A Biophysical Study
(Indian Institute of Science, 2006-10-17)In the cell, as in in vitro, the final conformation of a protein is determined by it's amino acid sequence (1). Some isolated proteins can be denatured and refolded in vitro in absence of extrinsic factors. However, in ... -
