Network Heterogeneities, Intrinsic Plasticity and Decorrelation in the Dentate Gyrus
A central premise for research in neuroscience is to mechanistically decipher the physiological roles of the brain in effectuating learning and memory. The tripartite framework that is at the core of learning and memory ... -
Neural Correlates and Behavioral Underpinnings of Remote Memories during Systems Consolidation
Remote retrieval of declarative memories has been under investigation for a long time. After acquisition, long-term encoding of memories happens through crosstalk across multiple brain regions. Through systems consolidation, ... -
Neural Mechanisms underlying the planning of sequential saccades
Saccades are rapid eye movements that we continually make (about 2-3 times per second) to look around and scan our visual environment. Though we effortlessly execute saccadic eye movements all the time, they are not just ... -
Neuronal complex bursts and network information transfer in the hippocampus are robust to biophysical heterogeneities
Biological entities must adopt mechanisms to override the impact of external perturbations to achieve stability and robustness. A crucial feature of biological systems is that they exhibit several forms of heterogeneities ... -
New Active Site Fold And The Role Of Metal Ions In Structure Function Relationship Of A Promiscuous Endonuclease - R.KpnI
(2010-07-08)Bacteria employ survival strategies to protect themselves against foreign invaders, including bacteriophages. The ‘immune system’ of bacteria relies mostly on restriction-modification (R-M) systems. The primary role of R-M ... -
New Anticancer Secondary Metabolites from an Endophytic Fungus Chaetomium Nigricolor Isolated from Catharanthus Roseus : Structural Elucidation and Molecular Mechanism Underlying Anticancer Effects
(2018-06-13)Cancer has become a major health problem due to its high rate of morbidity and mortality. Severe side effects associated with most of the available anticancer drugs and the development of the drug resistant cells are the ... -
New insights into the role of condensin in Saccharomyces cerevisiae
Structural Maintenance of Chromosomes (SMC) complexes are highly conserved from prokaryotes to eukaryotes. Saccharomyces cerevisiae has six SMC proteins which form three SMC-complexes in association with non-SMC subunits ... -
Newer Insights On Structure, Function And Regulation Of Dps Protein From Mycobacterium smegmatis
(2010-12-29)The first chapter will provide an introduction to the physiology, pathogenesis and biology of mycobacteria. Host-pathogen interactions, different modes of resistance of the bacteria, adaptations for survival under nutrient ... -
NMR Solution Structures of Human γC-Crystallin & the Intrinsically Disordered Viral Genome Linked Protein in the Free & Bound Form
(2018-02-14)This thesis describes the tertiary structures and dynamic studies of two protein systems. The first is human γC -crystallin protein, which is present in the nucleus of the human eye lens and the other is the plant viral ... -
Non-canonical functions of lymphoid-specific proteins AID and RAG1: Understanding mechanism, regulation, and implications in genomic instability
Recombination-activating genes (RAGs) and Activation-induced cytidine deaminase (AID) are lymphoid cell-specific proteins that play crucial roles in the development of adaptive immunity. Diversification of the immune system ... -
Non-repetitive Structures In Proteins : Effects Of Side-chain And Solvent Interactions With The Backbone
(Indian Institute of Science, 2006-05-12)The work presented in this thesis deals with the analysis of protein crystal structures with an emphasis on the stereochemical aspects of the folded conformation of proteins. The various analyses described have been performed ... -
Nonstructural Protein, NSs Encoded By Groundnut Bud Necrosis Virus (Tomato) Is A Multifunctional Enzyme
(2011-08-08)1 Viruses are submicroscopic obligate parasites that depend on the host cell for their growth and reproduction. Plants are infected by diverse group of viruses that mostly possess RNA as their genome. In the recent times, ... -
Notch1-Induced Survival Signaling And Its Implications In Cancer Therapeutics
(2009-04-15)Notch receptors and ligands are type I transmembrane proteins that regulate development and differentiation during cell-cell contact. There are four Notch receptor homologues and five notch ligands, identified in humans ... -
Notch3 Receptor : Activation Mechanism and Association with Ovarian Cancer
The Notch signaling influences a wide spectrum of cell fate decisions, both during development and in the adult organisms. This pleiotropic role of Notch signaling in humans is attributed partially to the presence of four ... -
