Characterization of a Staphylococcus aureus multi-enzyme complex involved in the phenotypic switch and host-pathogen interactions
RNA homeostasis is maintained by synchronizing RNA synthesis and RNA degradation. These processes are synchronized to growth conditions and environmental stimuli, thus enabling bacterial survival in diverse environmental ... -
Design and characterization of stabilized mutants of the SARS-CoV-2 Receptor Binding Domain
The global pandemic caused by SARS-CoV-2 has resulted in millions of deaths worldwide, highlighting the urgent need for effective vaccines. The trimeric spike glycoprotein, particularly the receptor-binding domain (RBD), ... -
How does familiarity change visual object representations ?
Familiarity with something implies having a close acquaintance with that item, generally acquired over a period of time. Apart from single items, we have experienced getting familiar with a pair of items (like a mouse and ... -
Studies on the translation initiation factors in bacteria and mitochondria
The process of protein synthesis is a fundamental and key event in living organisms. The process of translation initiation is assisted by specific proteins known as initiation factors. In bacteria, three initiation ... -
Investigating the maintenance of X- chromosome inactivation in extra-embryonic endoderm and epiblast stem cells
In eutherian female mammals, one of the X-chromosomes gets inactivated to compensate for the expression dosage of X-linked genes between the sexes. X-chromosome inactivation (XCI) serves as a paradigm of epigenetic memory ... -
The role of neuronal integrity in maintaining gut functions and homeostasis
This thesis investigates two main aspects of neuronal integrity and gut health. Firstly, it examines the intricate relationship between neuronal integrity and the maintenance of gut homeostasis in Drosophila melanogaster. ... -
Structural and functional characterization of human regulator of telomere elongation helicase 1 (RTEL1)
RTEL1 is an ATP-dependent DNA helicase that translocates on the single-stranded DNA (ssDNA) from 5′ to 3′ direction. It is an iron-sulfur (Fe-S) cluster and DEAH motif-containing helicase. RTEL1 has been shown to play ... -
Understanding the mechanism of host deacetylase SIRT1 and SIRT3 in the modulation of Salmonella pathogenesis
Host sirtuins are one of the important modulators of host immuno-metabolic regulation. However, the role of sirtuins in the modulation of the immune metabolism pertaining to Salmonellosis is largely unknown. Here, we ... -
Design of Immunogens Derived from the Conserved Stem of Influenza Virus Hemagglutinin
Influenza viruses can cause respiratory illnesses and are very contagious, leading to either pandemics or seasonal epidemics and resulting in significant mortality and morbidity rates. The main symptoms of the influenza ... -
Interaction of hnRNPK with RNA and characterization of its phase separation behavior
Heterogenous ribonucleoproteins (hnRNPs) are a class of proteins initially discovered to protect the nascent transcripts before they develop into primary mRNAs. They are involved in almost all the stages of mRNA metabolism, ... -
Determinants of protein stability and function inferred from saturation mutagenesis and next-generation sequencing
Proteins play a central role in all biological processes. Despite a similar underlying composition, they exhibit immense diversity in structures and functions, a subject of great interest. The research presented in this ... -
Plasticity Paradigms: Navigating Protein Conformational Dynamics and Phenotypic Variability in Biological Systems
The complex dynamics and responses of biological systems to environmental cues are shaped by their inherent plasticity and adaptability. This biological plasticity, operational at multiple levels - ranging from the molecular ... -
Deep mutational scanning to enhance immunogenicity and map antibody responses to HIV-1
Vaccines have proven effective against numerous viral diseases, yet the development of a successful vaccine for Human Immunodeficiency Virus (HIV-1) remains elusive. A key immunogen for vaccine design is the surface ... -
Computational investigation of peripheral membrane protein "Pleckstrin homology domain" and its regulation
The peripheral membrane protein repertoire is around 25% composed of the Pleckstrin homology domain (PHD). PHD are component of the multidomain protein and plays the role of an adaptor in recruitment of these proteins ... -
Structural insight into unique features of the Translational apparatus in Plants
Plants are constantly challenged with a variety of biotic and abiotic stress conditions. Being sessile, plants cannot evade these conditions. Most of these sudden changes in environmental conditions require a quick change ... -
Role of PdtaS-PdtaR two component signalling system in metabolic adaptation in Mycobacterium spp.
The ability to perceive and adapt to environmental fluctuations, both internal and external, is a fundamental characteristic of life across diverse organisms. Within the context of pathogenic bacteria such as Mycobacterium ... -
Role of the unstructured N-terminal region and interacting proteins on the function of Mycobacterium tuberculosis σA
A distinctive feature of the bacterial RNA polymerase is the modular organization. The core of this enzyme, comprised of a dimer of the α subunit assembles with the β, β', and ω subunit. The core RNA polymerase enzyme ... -
Astroglial development as the basis for the effects of early life stress on adult depressive-like behavior
This thesis investigates the enduring effects of early-life stress, specifically maternal separation, on astroglial population and the subsequent behavioral outcomes in adult mice. While the persistent impact of early-life ... -
Understanding protein structural excursions using residue networks and implications on biological function
The information required for a protein structure to fold into the native conformation is encoded in its sequence. Studying protein structures help to understand their biological function. Molecular interactions between ... -
Venomics of Medically Important yet Neglected Elapid Snakes of India and the Antivenomic Potential of Plant Extracts
India is considered the world's snakebite capital, where over 58,000 snakebite fatalities are registered annually. Most bites are primarily attributed to four snake species: the spectacled cobra (Naja naja), common krait ...
