This book was released on 2011-05-10 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transcription factors are the molecules that the cell uses to interpret the genome: they possess sequence-specific DNA-binding activity, and either directly or indirectly influence the transcription of genes. In aggregate, transcription factors control gene expression and genome organization, and play a pivotal role in many aspects of physiology and evolution. This book provides a reference for major aspects of transcription factor function, encompassing a general catalogue of known transcription factor classes, origins and evolution of specific transcription factor types, methods for studying transcription factor binding sites in vitro, in vivo, and in silico, and mechanisms of interaction with chromatin and RNA polymerase.
Download or read book Transcription Factors written by David Latchman and published by OUP Oxford. This book was released on 1999-04-08 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of the first edition five years ago, a wide range of new methodologies have been developed to facilitate studies on both isolated parts of the genome and the genome as a whole. This new edition has been updated and expanded so that it provides a comprehensive guide to the methods currently available to characterize the function and activity of an individual transcription factor. All the original chapters have been fully updated or rewritten and additional chapters cover the use of in vitro transcription assays, analysis of chromatin structure, use of the genomic binding site assay and analysis of transcription factor modifications. As with the previous edition, the book starts with a series of chapters concerned with characterizing the proteins binding to a specific DNA sequence and then a chapter on more detailed characterization of the protein itself. The next two chapters describe the isolation of cDNA clones encoding a transcription factor using oligonucleotides predicted from protein sequence and screening of a cDNA expression library. Chapter 6 deals with identification of transcription factors based on sequence homology analysis by both experimental screening and database searches. Chapter 7 is a new chapter that describes methods of identifying the target genes of a previously uncharacterized factor. The next chapters deal with analysis of transcription factor function. Chapter 8 deals with general techniques, and then the following chapters cover the specialized techniques of in vitro transcription assays using transcriptionally active nuclear extracts derived from rat brain, and analysis of the effect of transcription factors on chromatin structure. The final chapter describes methods for detecting the phosphorylation and glycosylation state of transcription factors.
Download or read book Role of Transcription Factors in Eukaryotic DNA Replication written by Vladimir Paredes Bermudez and published by . This book was released on 1998 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: The polyomavirus origin of DNA replication, a model for eukaryotic DNA replication, is comprised of the core origin and two auxiliary sequences, which enhance replication. One of the auxiliary sequences contains binding sites for numerous transcription factors and can be replaced by multiple sites for a specific transcription factor. The Gal4VP16 chimeric transactivator is capable of activating both viral and cellular DNA replication; however, the mechanism by which it promotes replication is not understood. Here we show that this prototypic acidic transactivator activates the polyomavirus replicon by promoting the binding to and subsequent unwinding of the viral origin by the viral encoded large T antigen. However, the mere binding of transactivation domains to components of the replisome (such as large T antigen) is not sufficient to promote replication. In our experimental conditions, both p53 and Gal4VP16 bind polyomavirus large T antigen but only Gal4VP16 promotes polyomavirus origin unwinding and DNA replication. Similarly, the Sp1 transcription factor, which binds SV40 large T antigen, does not enhance the unwinding of the SV40 origin, nor does a Gal4-Sp1 fusion protein does not promote the replication of a DNA that contains the SV40 origin in cis to 5 Gal4 sites. However, in vivo, the Sp1 and p53 binding sites are capable of promoting SV40 and Py DNA replication, respectively. Thus, the capacity of an activation domain to promote DNA replication relies on qualitative interactions with initiation proteins. Transcription factors may also promote DNA replication by recruiting histone-modifying complexes that can increase accessibility of origins to initiation factors. We present evidence that the fusion protein of the Gal4 DNA binding domain and human histone acetyltransferase Gcn5 promotes polyomavirus DNA replication. This effect requires a functional histone acetyltransferase activity.

This book was released on 2013-03-26 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Regulation of DNA Replication and Transcription explores basic processes of DNA replication and transcription in an effort to identify the mechanisms responsible for the release of genetic information and its role in the regulation of cellular events. Concerned with discovering the fundamental concept that might integrate and explain the wide range of existing lines of evidence, the author reports and interprets the results of experiments conducted in an impressive range of biological systems. Focused on complex mechanisms at the biochemical level, these studies allow analysis of the pathways involved when cells, organs and animal systems react to various trigger molecules derived from both living cells and exogenous sources. These include hormones, RNA, RNA fragments, alkaloids, actinomycin D, and phorbol esters, as well as chemical carcinogens and drugs. Comnining the results of these studies with his own extensive work in this field, the author is able to formulate a uniquely integrative biochemical model for the gene expression, demonstrating that both biological and chemically synthesized molecules can trigger the differential release of information from the DNA and thus influence cell transformation. Apart from its academic significance, the model offers high potential assistance in the search for ways to induce or control the expression of certain genes and, moreover, to promote differentiation of given cells in vitro as well as in situ.

Available in PDF, EPUB and Kindle. Book excerpt: The effort to sequence the human genome is now moving toward a c- clusion. As all of the protein coding sequences are described, an increasing emphasis will be placed on understanding gene function and regulation. One important aspect of this analysis is the study of how transcription factors re- late transcriptional initiation by RNA polymerase II, which is responsible for transcribing nuclear genes encoding messenger RNAs. The initiation of Class II transcription is dependent upon transcription factors binding to DNA e- ments that include the core or basal promoter elements, proximal promoter elements, and distal enhancer elements. General initiation factors are involved in positioning RNA polymerase II on the core promoter, but the complex - teraction of these proteins and transcriptional activators binding to DNA e- ments outside the core promoter regulate the rate of transcriptional initiation. This initiation process appears to be a crucial step in the modulation of mRNA levels in response to developmental and environmental signals. Transcription Factor Protocols provides step-by-step procedures for key techniques that have been developed to study DNA sequences and the protein factors that regulate the transcription of protein encoding genes. This volume is aimed at providing researchers in the field with the well-detailed protocols that have been the hallmark of previous volumes of the Methods in Molecular TM Biology series.

Download or read book DNA Protein Interactions written by A. Travers and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our understanding of the mechanisms regulating gene expression, which determine the patterns of growth and development in all living organisms, ultimately involves the elucidation of the detailed and dy namic interactions of proteins with nucleic acids -both DNA and RNA. Until recently the commonly presented view of the DNA double helix as visualized on the covers of many textbooks and journals - was as a monotonous static straight rod incapable in its own right of directing the processes necessary for the conservation and selective reading of genetic information. This view, although perhaps extreme, was reinforced by the necessary linearity of genetic maps. The reality is that the biological functions of both DNA and RNA are dependent on complex, and sometimes transient, three-dimensional nucleoprotein structures in which genetically distant elements are brought into close spatial proximity. It is in such structures that the enzymatic manipulation of DNA in the essential biological processes as DNA replication, transcription and recombination are effected - the complexes are the mediators of the 'DNA transactions' of Hatch Echols.
Download or read book Bacterial Transcription Factors and the Cell Cycle 2nd edition written by Morigen Morigen and published by Frontiers Media SA. This book was released on 2022-10-10 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analogous to the eukaryotic G1, S and M phase of the cell cycle, the bacterial cell cycle can be classified into independent stages. Slowly growing bacterial cells undergo three different stages, B-, C- and D-phase, respectively, while the cell cycle of fast-growing bacteria involves at least two independent cycles: the chromosome replication and the cell division. The oscillation in gene expression regulated by transcription factors, and proteolysis mediated by ClpXP, are closely correlated with progression of the cell cycle. Indeed, it has been shown that DnaA couples DNA replication initiation with the expression of the two oscillating regulators GcrA and CtrA, and the DnaA/GcrA/CtrA regulatory cascade drives the forward progression of the Caulobacter cell cycle. Furthermore, it has been found that: the DnaA oscillation in Eschericha coli and Caulobacter crescentus plays an important role in the cell cycle coordination; RpoS in Coxiella regulates the gene expression involved in the developmental cycle; the SigB and SinR transcription factors control whether cells remain in or leave a biofilm responding to metabolic conditions in Bacillus subtilis; similarly, BolA in most Gram-negative bacteria turns off motility and turns on biofilm development as a transcription factor; CtrA regulates cell division and outer membrane composition of the pathogen Brucella abortus; an essential transcription factor SciP enhances robustness of Caulobacter cell cycle regulation. Interestingly, transcription factors mediated metabolism fluctuations are also related to progression of the cell cycle. It has been shown that: CggR and Cra factors are involved in the flux-signaling metabolite fructose-1,6-bisphosphate; IclR mediates para-hydroxybenzoate catabolism in Streptomyces coelicolor; CceR and AkgR regulate central carbon and energy metabolism in alphaproteobacteria; and these metabolism changes affect cell growth. In line with the argument, AspC-mediated aspartate metabolism coordinates the E. coli cell cycle. However, the molecular mechanisms of maintaining the proper cell cycle progression through coordination of transcription factors mediated gene transcription oscillation, cellular metabolism with the cell cycle are not yet well-established. This Research Topic is intended to cover the spectrum of cell cycle regulatory mechanisms, in particular the coordination of transcription factor mediated gene transcription oscillations, and the cellular metabolisms associated with the cell cycle. We welcome all types of articles including Original Research, Review, and Mini Review. The subject areas of interest include but are not limited to: 1. Cell cycle coordination through gene expression and expression oscillation mediated by transcription factors. 2. Regulation of the cell cycle by proteolysis oscillation. 3. Coordination of the cell cycle with metabolism fluctuation. 4. DNA methylation fluctuation and the cell cycle. 5. Novel transcription factors and gene expression patterns associated with the cell cycle.
