Structural and functional insights into hybrid AT-less megaenzyme synthase (NRPS) and DNA-MsDps2 complexes using single particle cryo-EM
Microorganisms, mainly bacteria and fungi, are the producers of structurally diverse, complex organic compounds called as secondary metabolites. These metabolites include polyketides (PKs), non-ribosomal peptides (NRPs), ... -
Investigating the role of AMPK in mammary gland alveologenesis and lactation
AMP-activated kinase (AMPK) is an energy sensor that regulates cell growth and metabolism. Reports from our laboratory and others have shown the context-specific role of AMPK signaling in breast cancer. However, its role ... -

Urolithin-A mitigates synaptic dysfunctions associated with epilepsy through VDAC1 inhibition: A novel therapeutic approach
Urolithin-A mitigates synaptic dysfunctions associated with epilepsy through VDAC1 inhibition: A novel therapeutic approach Epilepsies are a group of neurological disorders with a prevalence of 70 million people worldwide ... -
Characterization of XRN2-mediated microRNA turnover mechanism and its pathophysiological significance in eukaryotes
MicroRNAs (miRNAs) are endogenous, small non-coding RNAs that are extensively involved in the posttranscriptional regulation of gene expression in eukaryotes. Comprehensive studies on miRNA expression and function have ... -
Flavivirus RNA replication: Probe development, structural dynamics, and role of zinc ions.
Flaviviruses share a typical genome architecture where the highly conserved UTRs flank a central coding region. They also share a common genome replication strategy called genome cyclization where the UTRs interact to form ... -
Dissecting the function of NuMA in cleavage furrow formation and chromatin decondensation at the mitotic exit in animal cells
In animal cells, the duplicated genetic material is aligned on a microtubule-based structure known as the mitotic spindle during mitosis. At the mitotic exit, the mitotic spindle elongates, and the sister chromatids get ... -
Parietal and prefrontal control of distinct components of attention
In this thesis, we investigate behavioural mechanisms and neural substrates of distinct components of endogenous spatial attention. Endogenous attention facilitates neural processing of the selected stimulus through one ... -
Systems biology approach to dissect Salmonella-host interactions
Systems understanding of the biological data is required to capture the complex biochemical information when a pathogen interacts with its host. Such interactions are dynamic and complex, especially because various components ... -
Studies on the promoter specificity determinants and modulators of the prokaryotic transcription machinery
Bacteria adapt to a wide range of environmental conditions by synchronizing transcription with changes in the extracellular environment. This is achieved by the synchronized action of two-component systems, Extra Cytoplasmic ... -
Development of 3D model and understanding translational regulation of breast cancer
Breast cancer is the most common cancer among women in India and worldwide. It is a highly heterogeneous disease caused by several genetic and epigenetic alterations in mammary epithelial cells. Both inter- and intra-patient ... -
Role of Sirt2 in Stress-induced Muscle Atrophy
Skeletal muscle is one of the essential organs in our body, responsible for various functions such as locomotion, transport, protein storage, and thermoregulation. Under certain pathological conditions, there is a reduction ... -
Investigation of anticancer compounds in the natural productome of marine algae associated-endophytic fungi
Cancer is one of the leading causes of death worldwide. Owing to the complex ways in which this disease develops, there is a constant demand for new drugs. Natural products have delivered great promise in inspiring ... -
Differential Regulation of Calcium Dependent Phase Separation and Modular Assembly of Sap97/Hdlg Enriched Molecular Complexes
Recent studies over a few decades have changed the perspective of the molecular architecture of functional zones within synapses and other cell junctions. Observations in the last decade confirm Post Synaptic Density as ... -
Biochemical and structural studies to provide insights into initiator tRNA delivery by eIF2A in noncanonical translation initiation
Eukaryotic initiation factor 2A (eIF2A), a non-canonical translation initiation factor, delivers initiator tRNA (tRNAi) onto the 40S ribosomal subunit in a codon-dependent and GTP-independent manner, unlike the canonical ... -
Epigenetic modulation of Foam cell generation during Mycobacterium tuberculosis/ Cryptococcus neoformans infection
Foamy macrophages or Foam cells are a critical cellular component of the granuloma formed during pulmonary infection. These lipid rich cells generally contain neutral lipids, Cholesteryl Esters (CE) and/or Triglycerides ... -
Metabolic Regulation of Gametocytogenesis in Malaria
Plasmodium sp. is an obligate intracellular protozoan parasite causing malaria and is responsible for more than 500,000 human deaths annually. P. falciparum and P. vivax are the two major species causing malaria in humans. ... -
Solution structures and interaction studies of mycobacterial MazEF6 toxin-antitoxin system
Toxin-Antitoxin (TA) systems are stress response systems found on plasmids and chromosomes of bacteria and archaea. They are involved in important functions such as plasmid maintenance, programmed cell death, persister ... -
Deciphering the role of outer membrane porins in the pathogenesis of Salmonella enterica serovar Typhimurium
Porins are highly conserved barrel-shaped proteins bound to the bacterial outer membrane and involved in the selective transport of charged molecules across the membrane. They consist of parallel and anti-parallel β sheets ... -
Effect of Stimulus Normalization and Visual Attention at multiple scales of Neural Integration
The effect of visual attention on neural signals has been extensively studied using various techniques such as macaque neurophysiology and human electro/magneto encephalogram (EEG/MEG). Depending on the technique, different ...
