Understanding the Biology of Heat Shock Protein 90 in Opportunistic Fungal Pathogens
Heat shock protein 90 is one of the most abundant and evolutionary conserved class of molecular chaperones present throughout the biological kingdom. It is a specialist chaperone as its function extends beyond protein ... -
Understanding the Dynamic Organization of the Presequence-Translocase in Translocation of Preproteins Across Mitochondrial Inner Membrane
(2018-05-08)Mitochondrion is an endosymbiotic organelle synthesizing ~1% of its proteome, while remaining ~99% of the proteins are encoded by the nuclear genome and translated on the cytosolic ribosome. Therefore active mitochondrial ... -
Understanding the Functions of Nucleoid Associated Proteins in Mycobacterium tuberculosis
The prokaryotic genome, though lacks a membrane bound organelle for its housing, is restricted to only about 25% of the cytoplasmic space called the nucleoid. The dramatic compaction required for the genome to fit in is ... -
Understanding the Heat Shock Response Pathway in Plasmodium Falciparum and Identification of a Novel Exported Heat Shock Protein
(2018-02-27)Infections or diseases are not just stressful for the one who encounters it. The pathogens causing the same also have to deal with the hostile environment present in the host. The maintenance of physiological homeostatic ... -
Understanding the interaction mechanism of bacterial virulence factors and effector proteins with host lipid membrane using single particle cryo-electron microscopy
Pathogenic bacteria employ an array of biological macromolecules and cellular structures that help in the initiation and progression of disease in host organism. These ‘virulence factors’ can either be secreted by the ... -
Understanding the Long-term Impact and Mechanism of Action of Endosulfan, an Organochlorine Pesticide on Fertility, Development and Growth of Mice
Endosulfan (ES) is one of the major broad-spectrum organochlorine pesticides categorized as Class II (moderately hazardous) by WHO and Class I (highly acutely toxic) by US Environment Protection Agency. Although the use ... -
Understanding the Mechanism of Double-strand Break Repair and Genome Fragility in Mammalian Mitochondria
Mitochondria are semiautonomous organelles in a cell as they have their own genome that replicates independently. It plays a major role in oxidative phosphorylation due to which mitochondrial DNA (mtDNA) is frequently ... -
Understanding the Mechanism of Homologous Recombination in Mycobacterium Tuberculosis : Exploring RecA as an Antibacterial Target and Characterization of Holliday Junction Resolvases
(2018-08-09)Homologous recombination (HR) is conserved across all three domains of life and is associated with a number of key biological processes. Over the years, numerous genetic, biochemical and structural studies have uncovered ... -
Understanding the Mechanism of Noncanonical Functions of RAGs in Lymphoid Cancer and Glioblastoma
Recombination activating genes (RAGs) composed of RAG1 and RAG2, are the endonuclease involved in V(D)J recombination, which is critical for adaptive immunity in mammals. Activation-induced cytidine deaminase (AID), expressed ... -
Understanding the mechanisms of polarity establishment and nuclear envelope breakdown in Caenorhabditis elegans embryos
Polarity establishment is critical for the development and stem cell lineages. The one-cell stage of the Caenorhabditis elegans embryo polarizes soon after fertilization. As a result, the first division of the embryo ... -
Understanding the origins and diversification of Indian blindsnakes
Much of systematics done in the past was based on morphological data. One of the drawbacks of using morphological data is that in groups with conserved morphology, the diversity is often underestimated and relationships ... -
Understanding the redox homeostatic mechanisms in Mycobacterium tuberculosis infection
Mycobacterium tuberculosis (Mtb) is an obligate intra-cellular pathogen that causes the disease tuberculosis (TB) in its human hosts. An estimated 1% of the world population is reported to get infected with the disease ... -
Understanding the Regulation of mRNA Translation Repression by RGG-motif Proteins
Messenger RNA translation is one of the most energy expensive steps in the process of gene expression and therefore translation regulation is critical for maintaining cellular homeostasis. In contrast to transcriptional ... -
Understanding the regulation of translation and replication of Coxsackievirus B3 RNA by host RNA binding proteins
Coxsackievirus B3 (CVB3) is an enterovirus, with a positive-sense single-stranded RNA genome. The genome contains a single open reading frame (ORF) flanked by untranslated regions (UTR) at the 5’ and 3’ ends. The viral ... -
Understanding the Regulatory Steps that Govern the Activation of Mycobacterium Tuberculosis σK
(2018-07-28)A distinctive feature of host-pathogen interactions in the case of Mycobacterium tuberculosis is the asymptomatic latent phase of infection. The ability of the bacillus to survive for extended periods of time in the host ... -
Understanding the role of arginine clusters in β-hairpin antimicrobial peptides
The work described in this thesis describes the role of arginine clusters and the importance of their position in B-hairpin antimicrobial peptides. Here, we have tried to explore the role of guanidinium groups in the ... -
Understanding the role of Cysteine desulfurases in Mycobacterium tuberculosis physiology and pathogenesis
The Mycobacterium tuberculosis (Mtb) persistence inside the human host relies on successful adaptation to host-induced stresses such as reactive oxygen species (ROS), reactive nitrogen species (RNS), iron starvation, low ... -
Understanding the role of DNAJC30 and ISCU in mitochondrial homeostasis
Williams-Beuren Syndrome (WBS) is a rare multisystem genomic disorder characterized by mild to moderate cognitive impairment, unique personality traits, distinctive facial features, cardiovascular problems, and infantile ... -
Understanding the role of hydrogen sulfide in regulating redox homeostasis and inflammation during cellular senescence
Aging involves the time-dependent deterioration of physiological functions, which can be attributed to various factors. Cellular senescence has been shown to be akin to aging, which involves alteration in redox homeostasis ... -
Understanding the Role of Lsm Domain in Translation Repression Activity of RGG-motif Containing Protein Scd6
Control of gene expression in eukaryotes is regulated at various steps such as transcription, translation and protein degradation. Translation repression of mRNA regulates protein levels and maintains cell homeostasis. ...
