Quantitative Proteome Analysis of Atg5-Deficient Mouse Embryonic Fibroblasts Reveals the Range of the Autophagy-Modulated Basal Cellular Proteome

Post Image

Autophagy performs housekeeping functions for cells and maintains a functional mode by degrading damaged proteins and organelles and providing energy under starvation conditions. The process is tightly regulated by the evolutionarily conserved Atg genes, of which Atg5 is one such crucial mediator. Here, we have done a comprehensive quantitative proteome analysis of mouse embryonic fibroblasts that lack a functional […]

Tetramerization at low pH licenses DNA methylation activity of M.HpyAXI in the presence of acid stress

Post Image

Methylation of genomic DNA can influence the transcription profile of an organism and may generate phenotypic diversity for rapid adaptation in a dynamic environment. M.HpyAXI is a type III DNA methyltransferase present in Helicobacter pylori and is upregulated at low pH. This enzyme may alter the expression of critical genes to ensure the survival of […]

Drosophila as a model system to study complex interactions that maintain immune and energy homeostasis

Post Image

As part of collaborative research Dr. Geetanjali Chawla participated in a study that examined the metabolic remodeling that occurs in macrophages during bacterial infection.  This work has revealed that orthologs of Hypoxia inducible factor 1a (HIF1a) and Lactate dehydrogenase (LDH) are required for macrophage activation, bactericidal function of the immune cells and resistance to infection, […]

A polar filter in DNA polymerases prevents ribonucleotide incorporation

Post Image

The presence of ribonucleotides in DNA can lead to genomic instability and cellular lethality. To prevent adventitious rNTP incorporation, the majority of the DNA polymerases (dPols) possess a steric filter in the form of a bulky residue that stacks against the ribose sugar and clashes with 2’ -OH of incoming ribonucleotide. MsDpo4 from Mycobacterium smegmatis, […]
