Understanding Patterns of Bird Species Distribution in the Western Ghats
(2018-06-23)Macroecology is the study of relationships between organisms and the environment at large spatial and temporal scales. This field of research examines patterns in species abundance, distribution and diversity. Understanding ... -
Understanding Phage MU Mom Regulation and Function
(2018-06-11)Mu is a temperate bacteriophage which infects Escherichia coli and several other Gram negative enteric bacteria. It is an extraordinary phage in several respects and has carved a special niche for itself both as a genetic ... -
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 ... -
Understanding Rules of Assembly and Species Interactions in Mixed-species Bird Flocks
In mixed-species bird flocks (flocks hereafter), participants vary in their degree of similarity with each other. Flock participants can gain group size (supplementary) benefits by choosing similar flock partners, or ... -
Understanding structure, function, and dynamics in macromolecular complexes
In the scope of my thesis work, a concerted effort was undertaken to elucidate bi- ological functions through the lens of structural analysis, employing protein dy- namics. The role of protein dynamics in shaping and ... -
Understanding the adaptive responses of Salmonella Typhimurium during bile stress
Salmonella Typhimurium (S. Typhimurium) is an enteric pathogen that causes gastroenteritis. Although gastroenteritis is usually non-life threatening in healthy adults, it can cause fatality in children and immunocompromised ... -
Understanding the architecture of mitochondrial presequence translocase machinery and its implications in ALS progression
The current thesis describes the structural organization of the presequence translocase machinery and its functional association with ALS pathogenesis. The TIM23 complex is essential for the mitochondrial biogenesis of ... -
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 ...
