Towards The Understanding Of The Structural Biology Of Histone H1
(Indian Institute of Science, 2005-11-23)In the eukaryotic nucleus, an immense length of DNA is compactly packaged to generate an ordered three-dimensional hierarchical structure called chromatin (van Holde, 1988; Wolffe, A.P, 1998). This organization forms a ... -
Transcriptional Regulation By A Biotin Starvation- And Methanol-Inducible Zinc Finger Protein In The Methylotrophic Yeast, Pichia Pastoris
(2016-05-04)Pichia pastoris, a methylotrophic yeast is widely used for recombinant protein production. It has a well characterized methanol utilization (MUT) pathway, the enzymes of which are induced when cells are cultured in the ... -
Transcriptional Regulation By Nuclear Receptor Homodimers Binding To The Direct Repeat Motif DR1 : Investigations In An in vitro Transcription System Derived From Rat Liver Nuclear Extracts
(Indian Institute of Science, 2005-11-23)Nuclear receptors (NRs) are important transcription factors involved in the regulation of a variety of physiological processes such as embryonic development, cell differentiation and homeostasis (for review, see Mangelsdorf ... -
Translational readthrough of AGO1 mRNA and its regulation by let-7a microRNA
During translation, the message encoded in mRNAs is decoded by ribosomes to synthesize proteins following strict canonical decoding rules. This process is tightly regulated and several mechanisms exist in cells that ensure ... -

(2009-05-21)Type-II Ribosome Inactivating Proteins from Abrus precatorius: Cytotoxicity and Mechanism of Cell Death A/B toxins produced by bacteria and plants are among the deadliest molecules known. The plant type-II ribosome ... -
Uncovering of a novel non-taxane anticancer secondary metabolite from Taxol-producing endophytic fungus: Optimization of culture parameters and whole-genome sequence analysis for improved taxane production biosynthesis.
Cancer-related mortalities and morbidities have proven to be a great health burden for human society with immense economic implications. With uncontrolled proliferation of cells as the fundamental principle underlying its ... -
Uncovering the Role of Mitochondrial Co-chaperones and Artificial Antioxidants in Cellular Redox Homeostasis
(2018-02-14)The role of mitochondria is multidimensional and ranges in vast areas, including apoptosis, cellular response towards stress, metabolism, which is regulated by a plethora of proteins, acting together to maintain cellular ... -
Uncovering the Role of Mitochondrial Iron-sulfur (Fe-S) Cluster Biogenesis in Human Health and Disease
(2018-09-04)Mitochondrial dysfunction has been implicated for a wide range of human diseases. One of the major biosynthetic processes in human mitochondria is the biogenesis of Iron-Sulfur (Fe-S) clusters which primarily involves in ... -
Uncovering the role of NFS1 in Fe-S cluster biogenesis and in the development of Infantile mitochondrial complex II/III deficiency (IMC23D) disease progression and 2. Screening single domain antibody (VHH) against a membrane transporter
The mitochondrion is a double membrane-bound organelle found in all eukaryotic organisms. Mitochondria are endosymbiotic, autogenous organelles referred to as “Powerhouse” of cells due to their ability to synthesize ATP ... -
Understanding Heat Shock Protein 90 Biology And Exploring Its Potential As A Target Against Neglected Protozoan Diseases
(2013-04-04)Cells invest a lot of energy in order to get their proteins to fold correctly and attain functionality. It is the functional proteome of a cell that defines the ‘life of a cell’. Cells have therefore employed dedicated ... -
