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.

Recent evidence proving the molecular link between unchecked, chronic inflammation and cancer has implicated the transcription factor NF-kB as a key factor in both inhibiting apoptosis and promoting cell proliferation. Since its initial identification 20 years ago as a simple regulating factor in one small part of the immune response, NF-kB is prov
Several general principles have emerged from the study of human transcription factors. First, germline mutations in genes encoding transcription factors result in malformation syndromes in which the development of multiple body structures is affected. Second, somatic mutations involving many of the same genes contribute to tumorigenesis. Third, transcriptional regulatory mechanisms demonstrate remarkable evolutionary conservation. Fourth, prenatal development and postnatal physiology are unified by the demonstration that a single transription factor can control the proliferation of progenitor cells during development and the expression within the differentiated cells of gene products that participate in specific physiologic responses. Transcription Factors and Human Disease presents the basic science of transcriptional regulation and then describes inherited human diseases attributable to mutations in DNA sequences encoding transcription factors or their cognate binding sites. The involvement of transcription factors in somatic cell genetic diseases (cancer) and epigenetic disease (teratogenesis) is briefly discussed. The effect of specific mutations on transcription factor activity and the relationship between transcriptional dysregulation, dominant or recessive inheritance patterns, and disease pathogenesis are also explored. This book thus provides a direct connection between molecular defects in transcriptional regulation and human pathophysiology.
Now in two-colour throughout, the fourth edition of Eukaryotic Transcription Factors has been completely rewritten and restructured to take into account the tremendous advances in our understanding of transcription factors and the mechanisms by which they act. Considerable emphasis has been given to the interaction between transcription factors and chromatin structure. Also included is an entirely new section on the mediator complex and expansion of the space devoted to co-activators and co-repressors.This book is essential reading for all those who wish to understand the impact of molecular biology on medicine, whatever their speciality. - Major families of eukaryotic transcription factors described - Mechanisms of gene activation and repression analysed - Structure-function relationships indicated - Interaction between transcription factors and chromatin structure described - Roles in inducible and cell type-specific gene expression - Roles in development, differentiation and human diseases including cancer - Methods of study in vitro and in vivo
Transcription factors are important in regulating gene expression, and their analysis is of paramount interest to molecular biologists studying this area. This book looks at the basic machinery of the cell involved in transcription in eukaryotes and factors that control transcription in eukaryotic cells. It examines the regulatory systems that modulate gene expression in all cells,a s well as the more specialized systems that regulate localized gene expression throughout the mammalian organism. Transcription Factors updates classical knowledge with recent advances to provide a full and comprehensive coverage of the field for postgraduates and researchers in molecular biology involved in the study of gene regulation.
With contributions by numerous experts
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.
Covers the conceptual and practical aspects of how to study the regulation of a newly isolated gene and the biochemistry of a new transcription factor. This book puts methods in the context of underlying theory, and offers recommendations on experimental strategies.
Plant Transcription Factors: Evolutionary, Structural and Functional Aspects is the only publication that provides a comprehensive compilation of plant transcription factor families and their complex roles in plant biology. While the majority of information about transcription factors is based on mammalian systems, this publication discusses plant transcription factors, including the important aspects and unifying themes to understanding transcription factors and the important roles of particular families in specific processes. - Provides an entry point for transcription factor literature - Offers compilation of information into one single resource for rapid consultation on different plant transcription factor features - Integrates the knowledge about different transcription factors, along with cross-referencing - Provides information on the unique aspects surrounding plant transcription factors
