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 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 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 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 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 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. ... -
Understanding the role of mtHsp70 in regulating mitochondrial homeostasis: revealing its significance in Congenital Sideroblastic Anemia progression
Mitochondria are ubiquitous organelles placed at the nexus of several metabolic and signaling pathways essential for cell survival. Therefore, maintaining a healthy and functional organelle becomes paramount for the cell. ... -
Understanding the Role of ThiJ/DJ-1/PfpI Family Member Proteins in Regulating Redox Homeostasis, Mitochondrial Health and Lifespan in Saccharomyces cerevisiae
In a healthy cell, the ROS levels are stringently regulated by the action of various enzymatic or non-enzymatic antioxidant systems. Imbalance in the ROS homeostasis generates oxidative stress resulting in damage to cellular ... -
Understanding the Sequence Dependence of NHEJ Mediated Double-strand Break Repair, and Identification of Novel DNA Ligase Inhibitors and their Potential Use as Cancer Therapeutics
Repair of DNA breaks is essential for maintenance of genomic integrity. DNA double-strand breaks (DSBs) are considered as the most harmful DNA lesions within the cells which if left unrepaired or are misrepaired, can lead ... -
Understanding the structural organization of the carrier translocase machinery in regulating mitochondrial biogenesis and organelle quality control
Mitochondria are essential eukaryotic organelles required for diverse cellular functions including, energy homeostasis, iron-sulfur cluster biogenesis, and signaling. Therefore, the maintenance of organelle quality control ... -
Unfolded Protein Response in Malaria Parasite
(2018-01-28)Plasmodium falciparum is responsible for the most virulent form of human malaria. The biology of the intra-erythrocytic stage of P. falciparum is the most well studied as it is this stage that marks the clinical manifestation ... -
