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 ...
Studies on the roles of rffG and rfbB encoding dTDP-glucose 4,6- dehydratase in Salmonella Typhimurium
Salmonellosis is a major health concern which causes significant morbidity and mortality worldwide. Infection with Salmonella Typhimurium leads to self-limiting diarrhea in healthy individuals and invasive disease in ...
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 ...
The dual-targeting of Saccharomyces cerevisiae Pso2 into the nucleus and mitochondria is regulated by post-translational modifications: Implications for organelle-specific DNA repair
The repair of DNA interstrand crosslinks (ICLs) involves the concerted action of multiple DNA repair pathways. In eukaryotes, ICLs are sensed and repaired by replication-coupled or replication-independent mechanisms in ...
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 ...
Functional characterization of Salmonella Typhimurium encoded Cold Shock Protein E during stress responses, biofilm formation and virulence
Overall, this study reports novel functional roles of S. Typhimurium encoded CspE during bile resistance, biofilm formation and in vivo virulence. It also establishes importance of an uncharacterised protein YciF, implicating ...
Understanding Nonhomologous DNA End Joining: Novel Insights Into Mechanism and Regulation
This study has provided new insights into the mechanistic details of NHEJ
and showed that DNA sequence around the break site can be a factor in determining which
proteins involved in NHEJ might be recruited with a higher ...
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 ...
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 ...
Understanding the Mechanism of Noncanonical Functions of RAGs in Lymphoid Cancer and Glioblastoma
Recombination activating genes (RAGs) composed of RAG1 and RAG2, are the endonuclease involved in V(D)J recombination, which is critical for adaptive immunity in mammals. Activation-induced cytidine deaminase (AID), expressed ...
