Download or read book Mapping the Interactions of the Multi Subunit General Transcription Factor IIIB TFIIIB with U6 Promoter DNA by Site Specific Protein DNA Photo Cross Linking written by Jin Joo Kang and published by . This book was released on 2016 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: U6 small nuclear RNA (snRNA) functions as a component of the spliceosome and is required to splice eukaryotic pre-mRNAs. Although the other spliceosomal snRNAs are synthesized by RNA polymerase II, U6 snRNA is synthesized by RNA polymerase III. The genes that code for U6 snRNA have promoters that are completely gene-external, that is, in the 5'-flanking DNA. These promoters contain a TATA box, as well as a required upstream proximal sequence element (PSE) that is unique to snRNA genes. The PSE is recognized by a multi-subunit transcription factor SNAPc, whereas the TATA sequence is bound by the general transcription factor TFIIIB, which is responsible for assembling an RNA polymerase III initiation complex. In the fruit fly Drosophila melanogaster, TFIIIB is composed of three distinct subunits that assemble on the U6 promoter: TBP, Bdp1 and Brf1. [On tRNA and 5S rRNA promoters in fruit flies, TRF1 (TBP-related factor 1) is employed in place of TBP.] At the present time, the overall structures of TFIIIB and particularly the Brf1 and Bdp1 subunits are not well known. To better understand the mode of fruit fly TFIIIB binding to DNA, I have used site-specific protein-DNA photo-cross-linking. I introduced photo-cross-linker at every second phosphate position in the DNA backbone on both the template and non-template strands within and surrounding the fly U6 TATA box. I have in this manner mapped the locations where each of the TFIIIB subunits lies in close proximity to the DNA. Brf1 cross-links strongly to the DNA within and upstream of the TATA box, whereas Bdp1 cross-links strongly both upstream and downstream but not within the TATA sequence. The data indicate that Bdp1 lies on the DNA in close proximity to two subunits of DmSNAPc. Bdp1 may therefore play a primary role in the recruitment of TFIIIB to the U6 promoter through interactions with DmSNAPc.

Download or read book Drug Discovery in Cancer Epigenetics written by Gerda Egger and published by Academic Press. This book was released on 2015-11-19 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drug Discovery in Cancer Epigenetics is a practical resource for scientists involved in the discovery, testing, and development of epigenetic cancer drugs. Epigenetic modifications can have significant implications for translational science as biomarkers for diagnosis, prognosis or therapy prediction. Most importantly, epigenetic modifications are reversible and epigenetic players are found mutated in different cancers; therefore, they provide attractive therapeutic targets. There has been great interest in developing and testing epigenetic drugs, which inhibit DNA methyltransferases, histone modifying enzymes or chromatin reader proteins. The first few drugs are already FDA approved and have made their way into clinical settings. This book provides a comprehensive summary of the epigenetic drugs currently available and aims to increase awareness in this area to foster more rapid translation of epigenetic drugs into the clinic. Highlights the potential of epigenetic alterations in cancer for drug development Covers the tools and methods for epigenetic drug discovery, preclinical and clinical testing, and clinical implications of epigenetic therapy Provides important information regarding putative epigenetic targets, epigenetic technologies, networks and consortia for epigenetic drug discovery and routes for translation

Available in PDF, EPUB and Kindle. Book excerpt: Molecules to Medicine with mTOR: Translating Critical Pathways into Novel Therapeutic Strategies is a one-stop reference that thoroughly covers the mechanistic target of rapamycin (mTOR). mTOR, also known as the mammalian target of rapamycin, is a 289-kDa serine/threonine protein kinase that is ubiquitous throughout the body and has a critical role in gene transcription and protein formation, stem cell development, cell survival and senescence, aging, immunity, tissue regeneration and repair, metabolism, tumorigenesis, oxidative stress, and pathways of programmed cell death that include apoptosis and autophagy. Incorporating a translational medicine approach, this important reference highlights the basic cellular biology of mTOR pathways, presents the role of mTOR during normal physiologic function and disease, and illustrates how the mechanisms of mTOR can be targeted for current and future therapeutic treatment strategies. Coverage of mTOR signaling includes the entire life cycle of cells that impacts multiple systems of the body including those of nervous, cardiovascular, immune, musculoskeletal, endocrine, reproductive, renal, and respiratory origin. Covers the role of mTOR by internationally recognized expert contributors in the field. Provides a clear picture of the complexity of mTOR signaling as well as of the different approaches that could target this pathway at various levels.
