Regulation of carbon metabolism in Pichia pastoris by Mxr1p and identification of novel regulators
Pichia pastoris (a.k.a. Komagataella phaffii), a widely used yeast for recombinant protein production, is cultured under a variety of conditions ranging from shake flasks to large bioreactors employing minimal, chemically ... -
Regulation of Flagellar Motility in Giardia lamblia and Trichomonas vaginalis
Protozoan pathogens are responsible for infections that are highly prevalent, especially in developing and under-developed countries. Flagellar motility is exhibited by a variety of organisms ranging from bacteria to certain ... -
Regulation of RecA nucleoprotein filament stability by RecX and the effects of RecA-membrane interaction on the activities of RecA in mycobacteria
E. coli RecA is a multifunctional protein known to be associated with the cell membrane, forming foci often located at the cell poles, which gets redistributed along the length of the cell during SOS response. Several lines ... -
A role for the cohesin complex in subtelomeric gene silencing in Saccharomyces cerevisiae
Chromatin is a dynamic structure which reorganizes to support numerous chromosomal processes. Various histone and non-histone proteins are involved in chromatin organization. One such group of non-histone proteins, known ... -
Role of Escherichia coli UvrD helicase in resolving G-quadruplex DNA structures
G-quadruplex (G4) secondary structures have been implicated in various biological processes, including gene expression, DNA replication and telomere maintenance. However, unresolved G4 structures impede replication ... -
Role of Grp 75 Chaperone Folding Machinery in the Maintenance of Mitochondrial Protien Quality Control
(2018-04-03)My research focuses on understanding the importance of human mitochondrial Hsp70 (Grp75) chaperone machinery for the maintenance of protein quality control inside the mitochondrial matrix. The investigations carried out ... -
Role of Mammalian RAD51 Paralogs in Genome Maintenance and Tumor Suppression
(2018-01-28)My research was focused on understanding the importance of mammalian RAD51 paralogs in genome maintenance and suppression of tumorigenesis. The investigation carried out during this study has been addressed toward gaining ... -
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. ...
