Structural and Functional Studies on Pyridoxal Kinase and Pyridoxal 5′-phosphate Dependent Enzymes
(2018-07-04)Most of the chemical reactions of living cells are catalyzed by protein enzymes. These enzymes are very efficient and display a high degree of specificity with respect to the reaction catalyzed. Cellular activities depend ... -
Molecular Insights into Lymphoid Malignancy : Role of Transcription Factor BCL11B in T-cell Leukemia Genesis and Biochemical Characterization of DNA Binding Domain of RAG1
(2018-06-29)The lymphoid tissues consist of distinct cell subpopulations of B and T cell lineages and possess complex signaling pathways that are controlled by a myriad of molecular interactions. During the fine-tuned developmental ... -
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 ... -
Role of the ELONGATED GYNOPHORE/ELONGATA2 Protein in Fruit and Root Development in Arabidopsis Thaliana
(2018-06-23)In order to identify new players in fruit development, a forward genetic screen was performed on EMS mutagenized plants. A mutant named elongated gynophore (egy) was identified in the M2 population based on altered fruit ... -
Modulation of Protein Stability and Function by Cysteine Mutations and Signal Peptides
(2018-06-23)Chapter 1gives a general introduction to the CXXC motif found in natural proteins. It then reviews the studies where disulphides were engineered in various proteins. The various strategies developed to engineer metal binding ... -
Design and Characterization of HIV-1 ENV Derived Immunogens
(2018-06-21)The Human Immunodeficiency Virus (HIV) is a member of the retroviridae family from lentivirus genus which primarily infects CD4+ T cells and also to lesser degree monocytes, macrophages, and dendritic cells causing progressive ... -
Novel Facets of Heat Shock Protein 90 in Neglected Protozoan Parasites
(2018-06-18)Among molecular chaperones, Heat shock protein 90 (Hsp90) is unique in that its functions extend beyond protein folding. Hsp90 is universally present across the biological kingdom. While the primitive archaebacteria carry ... -
Dynamics of Invariant Object Representations in the Monkey Inferotemporal Cortex
(2018-06-18)Vision is computationally challenging because objects in the real world can change in size, position, viewpoint etc., and therefore cast a myriad images on the retina. Viewpoint changes are particularly challenging because ... -
Structural and Related Studies on Mycobacterial RecA and LexA
(2018-06-18)Genetic material of bacteria is subject to damage due to multitudinous factors, both extrinsic and intrinsic in origin. Mechanisms for the maintenance of genomic integrity are thus essential for a bacterium to survive. ... -
Immunomodulatory Activity of Glycodelin : Implications in Allograft Rejection
(2018-06-15)Glycodelin, a homodimeric glycoprotein belonging to the lipocalin superfamily, is synthesised predominantly by the cells of the reproductive system of certain primates including humans. Of the four different known glycoforms ... -
Spermatogenomics : Correlating Testicular Gene Expression to Human Male Infertility
(2018-06-13)Spermatogenesis is a complex and coordinated process of formation of sperms from the precursor spermatogonia, occurring inside the unique environment existing in the seminiferous epithelium. This process of development, ... -
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 ... -
Bone Morphogenesis Protein (BMP) Signaling at the Cross-roads of Host-Pathogen Interactions : Implications for Pathogenesis
(2018-06-13)Study of cell signalling pathways affected by pathogen entry comprises a fundamental aspect of understanding host-pathogen interactions. In this respect, the current study attempted to ascribe novel roles to Bone Morphogenesis ... -
The Role of Saccharomyces Cerevisiae MRX Complex and Sae2 in Maintenance of Genome Stability
(2018-06-11)In eukaryotes, the repair of DSBs is accomplished through two broadly defined processes: Non-Homologous End Joining (NHEJ) and Homologous Recombination (HR). The central step of HR is pairing and exchange of strands between ... -
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 ... -
Molecular Ecology of the Primitively Eusocial Wasp Ropalidia Marginata : Relatedness, Queen Succession and Population Genetics
(2018-06-08)Altruism is defined as a trait in an individual that increases some other individual’s fitness at the expense of her own. Therefore, existence of such traits in a population is an evolutionary paradox, as natural selection ... -
Solution Structures and Dynamics of Conotoxins and Small MutS Related Domain from Helicobacter Pylori MutS2
