Role of mammalian RAD51 paralogs in replication stress response and genome maintenance
The focus of my research has been to understand the molecular mechanisms underlying the role of mammalian RAD51 paralogs in genome maintenance and tumor suppression. The investigation carried out during this study has ... -
Role of Mycobacterium tuberculosis DinG and UvrD helicases in unwinding G-quadruplex DNA
Recent studies have demonstrated the role of E. coli UvrD as a replicative helicase that facilitates replication of rolling circle plasmids. Along with dinG and rep helicase, UvrD a so-called “accessory helicase” removes ... -
Role of Mycobacterium Tuberculosis RecG Helicase in DNA Repair, Recombination and in Remodelling of Stalled Replication Forks
(2018-05-14)Tuberculosis, caused by the infection with Mycobacterium tuberculosis remained as a major global health challenge with one third of world population being infected by this pathogen. M. tuberculosis can persist for decades ... -
Role of Mycobacterium tuberculosis UvrD1 and UvrD2 helicases in resolving G-quadruplex DNA structures
Unresolved G-quadruplex (G4) DNA secondary structures impede DNA replication and can lead to DNA breaks and to genome instability. Helicases are known to unwind G4 structures and thereby facilitate genome duplication. ... -
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 ... -
Roles of Protein Acetylation in the Human Pathogen Helicobacter pylori
Helicobacter pylori is a gram-negative epsilon proteobacterium infecting half of the world population. H. pylori is a naturally competent bacterium with a huge repertoire of Restriction-Modification (RM) systems. The ... -
Selective Binding Of Meiosis-Specific Yeast Hop1 Protein, or Its ZnF Motif, To The Holliday Junction Distorts The DNA Structure : Implications For Junction Migration And Resolution
(2010-09-30)Saccharomyces cerevisiae HOP1, which encodes a component of the synaptonemal complex, plays an important role in both gene conversion and crossing over between homologs, as well as enforces the meiotic recombination ... -
Stop codon readthrough in MTCH2 mRNA and its role in mitochondrial physiology
Stop codon readthrough is the process in which translation continues beyond a stop codon till a downstream, in-frame stop codon generating a polypeptide with a C-terminal extension. MTCH2 was selected as a potential ... -
Structural and Biochemical Analysis of DNA Processing Protein A (DprA) from Helicobacter Pylori
(2018-05-09)H. pylori has a panmictic population structure due to high genetic diversity. The homoplasy index for H. pylori is 0.85 (where 0 represents a completely clonal organism and 1.0 indicates a freely recombining organism) which ... -
Structural And Functional Characterization Of Calcium-Dependent Protein Kinase (CaCDPK1) From Cicer Arietinum : Effects Of Autophosphorylation And Membrane Phospholipids
(2016-07-11)In plants, calcium is a ubiquitous signaling molecule and changes in cytosolic calcium levels reported in response to various abiotic and biotic stresses like salt stress, drought, pathogen attack and phytohormone signaling. ... -
Structural and Functional Characterization of Quadruplex DNA Structures in Human Acetyl-CoA Carboxylase 1 Gene Promoters and Stabilization of G-quadruplex DNA by Carbazole-benzimidazole Conjugates
A number of studies have established that DNA targeting is a successful strategy in anticancer therapy. In recent years, however, the focus has shifted from double-stranded DNA to alternative DNA motifs such as G-quadruplex ... -
Structure Elucidation and Biological Evaluation of a Novel Steroidal Saponin, Cholestanol Glucoside Isolated from Saraca Asoca Enodophytic Fuungus, Lasiodiplodia Theobromae
(2018-05-16)Although the molecular mechanisms underlying the onset and progression of cancer has been unraveled to a great extend, cancer continues to remain a leading cause of death around the world. Clinical efficacy of the existing ... -
Structure-Function Relationships of Saccharomyces Cerevisiae Meiosis Specific Hop 1 Protein : Implications for Chromosome Condensation, Pairing and Spore Formation
(2018-03-07)Meiosis is a specialized type of cell division essential for the production of four normal haploid gametes. In early prophase I of meiosis, the intimate synapsis between homologous chromosomes, and the formation of chiasmata, ... -
Studies On Cloning And Characterization Of GnRH Receptor From The Pituitary Of Bonnet Monkey (Macaca Radiata) And Functional Studies With The Antiserum To GnRH Receptor
(Indian Institute of Science, 2005-11-23)GnRH is a decapeptide hormone, which plays a major role in the process of mammalian reproduction. It is synthesized by the hypothalamus and binds to its cognate receptor on the pituitary, to bring about the release of ... -
Studies On DNA Mismatch Repair Nicking Endonucleases Of Haemophilus Influenzae And Neisseria Gonorrhoeae
(2010-01-01)DNA mismatch repair ensures faithful transmission of genetic material from parents to progeny, which is required for the survival of the organism. The studies on E. coli MMR proteins have formed the basis for the study ... -
Studies On Heat Shock Protein 60 From Plasmodium Falciparum
(2010-09-14)Malaria is caused by a protozoan parasite belonging to the genus Plasmodia. Plasmodium falciparum is responsible for the fatal form of human malaria. Spread of drug resistant parasites warrants for sound biological ...
