Internalized membrane proteins are either transported to late endosomes and lysosomes for degradation or recycled to the plasma membrane. Although proteins involved in trafficking and sorting have been well studied, far less is known about the lipid molecules that regulate the intracellular trafficking of membrane proteins. We studied the function of(More)
Adenosine triphosphate (ATP) synthase β, the catalytic subunit of mitochondrial complex V, synthesizes ATP. We show that ATP synthase β is deacetylated by a human nicotinamide adenine dinucleotide (NAD(+))-dependent protein deacetylase, sirtuin 3, and its Drosophila melanogaster homologue, dSirt2. dsirt2 mutant flies displayed increased acetylation of(More)

The sphingolipid ceramide elicits several stress responses, however, organisms survive despite increased ceramide but how they do so is poorly understood. We demonstrate here that the AKT/FOXO pathway regulates survival in increased ceramide environment by metabolic adaptation involving changes in glycolysis and lipolysis through novel downstream targets.(More)
Retrotransposons (RT) constitute a major fraction of plant genome. They are implicated in evolution and sequence organization. These elements have been proposed to have major role in evolution and variation in genome size. The sequence information of these RT regions in terms of divergence and conservation could be utilized for determining the(More)
Scopolamine is widely used for its anticholinergic properties. Because of higher physiological activity and less side effects the world demand of scopolamine is estimated to be ten times greater than other anticholinergic agents, hyoscyamine and atropine. Since natural production is limited, alternatives are required to boost the production. We report the(More)
INTRODUCTION Landsteiner ABO system of blood groups is most important for transfusion medicine and has subtypes of A Antigen, A1 and A2, upon which further groups of A and AB have been classified. Of individuals with A antigen, approximately 20% belong to A2 while rest 80% belong to A1. Anti-A1 Lectin, a cold agglutinin which destroys A1 cells is clinically(More)
