SRF regulates the generation of neuroprotective astrocytes in the brain
In response to injuries, infections or in neurodegenerative disorders, astrocytes get activated to become reactive. This phenomenon is called astrogliosis and is marked by a spectrum of changes which encompasses structural, ... -
Stimulus statistics and HCN current mediated resonance sets the scale of input-output mapping in Stellate cells of the Medial Entorhinal Cortex
The functional significance of the computations performed by Stellate cells of the Medial Entorhinal Cortex, proven time and again, makes them insightful, yet intriguing. The gradients of the intrinsic properties of these ... -
Structural and biochemical studies on mycobacterial Uracil-DNA glycosylase (Ung) and MutT1, key proteins involved in maintaining the genomic integrity in Mycobacteria
Maintaining genomic integrity is indispensable for the survival and propagation of an organism. Failure to do so can cause mutations involving structural and functional aberrations, leading to severe diseases. The causative ... -
Structural and Biophysical studies to evaluate the influence of oligomerization on biomolecular function
Oligomeric proteins are more common than monomers. This aspect of molecular evolution substantially contributes to functional diversity and the acquisition of features such as cooperativity and regulatory mechanisms. Not ... -
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), ... -
Structural and functional insights of biological macromolecules associated with infectious diseases – single particle cryo-electron microscopy based studies
In the global context, particularly in India, the two most important infectious diseases among many others are Tuberculosis (TB), an age-old disease and COVID-19, a new-age disease. This thesis focuses on some of the key ... -
Structural and mechanistic studies on Staphylococcal RNA degrading enzymes and multienzyme complexes
RNA degrading enzymes and multi-enzyme complexes govern a variety of cellular processes. The role of these enzymes and multi-enzyme assemblies has been suggested to govern gene expression levels in bacteria with modulations ... -
Structural insights into assembly and regulation of HigBA toxin-antitoxin system from Escherichia coli
In the last few decades, bacterial Toxin-antitoxin (TA) systems have been identified to play crucial roles in bacterial survival under stressful conditions and virulence. TA systems are pair of genetic elements where one ... -
Structure-Function Analysis of Focal Adhesion Protein Vinculin in Neocortical Axon Growth and Development
Axon growth and extension are dependent on the interaction of neurons with extracellular matrix (ECM). The interaction between cells and ECM is known as focal adhesion (FA). Vinculin is one the major proteins of FA complex ... -
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 ... -
Untangling the Helicobacter pylori genome: Deciphering the significance of zinc finger motif(s) in Topoisomerase I catalysis
Helicobacter pylori, a human pathogen dominating gastric microbial population, displays differential gene expression during various stages of stomach colonization. Topoisomerases play a crucial role in maintaining DNA ... -
Use of strategically designed protein-like sequences in structure and function recognition
The advent of high fidelity protein sequencing techniques has led to a considerable wealth of sequence data. However, the number of proteins with information on 3-D structure and functional features available is considerably ...
