Available in PDF, EPUB and Kindle. Book excerpt: In the early 1980s, a few scientists started working on a Xenopus transcription factor, TFIIIA. They soon discovered a novel domain associated with zinc, and named this domain "zinc finger. " Th e number of proteins with similar zinc fingers grew quickly and these proteins are now called C2H2, Cys2His2 or classical zinc finger proteins. To date, about 24,000 C2H2 zinc finger proteins have been recognized. Approximately 700 human genes, or more than 2% of the genome, have been estimated to encode C2H2 finger proteins. From the beginning these proteins were thought to be numerous, but no one could have predicted such a huge number. Perhaps thousands of scientists are now working on C2H2 zinc finger proteins fi-om variou s viewpoints. This field is a good example of how a new science begins with the insight of a few scientists and how it develops by efforts of numerous independent scientists, in contrast to a policy-driven scientific project, such as the Human Genome Project, with goals clearly set at its inception and with work performed by a huge collaboration throughout the world. As more zinc finger proteins were discovered, several subfamilies, such as C2C2, CCHC, CCCH, LIM, RING, TAZ, and FYVE emerged, increasing our understanding of zinc fingers. The knowledge was overwhelming. Moreover, scientists began defining the term "zinc finger" differently and using various names for identical zinc fingers. These complications may explain why no single comprehensive resource of zinc finger proteins was available before this publication.

Available in PDF, EPUB and Kindle. Book excerpt: To investigate protein-DNA interactions, particularly the mechanism of DNA binding by Type III monomeric nuclear receptors, this work focuses on the human estrogen related receptor 2 (hERR2) in association with its consensus recognition element. The structure of hERR2 bound to an extended half-site was determined in solution by high resolution NMR methods. The structure explains how Type III monomeric nuclear receptors extend the specificity beyond the single half-site and overcome the requirement to bind cooperatively as dimers. The C-Terminal Extension (CTE) flanking the core DBD uses a modified adenine-thymine binding motif to accommodate the exocyclic amino group on a guanine nucleotide in the minor groove. Residues in the CTE then stabilize the complex by packing against a region of the core DBD normally reserved for dimerization. Mutation of residues involved in DNA-induced intramolecular packing significantly reduces the affinity of hERR2 for DNA. The importance of the interactions in the minor groove are examined by an investigation of the relative binding properties of hERR2 and small synthetic ligands, polyamides, which interact site-specifically in the minor groove. Polyamides designed to bind to the same region of the minor groove as the CTE of hERR2 were shown to inhibit hERR2 binding. These studies identified a novel mechanism for extending the specificity outside of the half-site and stabilizing the monomer through DNA-induced intramolecular interactions. A preliminary study was carried out using C2H2 zinc fingers from TFIIIA and p43 that associate with 5S RNA. Differences in the thermodynamic properties of the full length proteins with 5S RNA were localized to interactions between three finger constructs and a truncated version of the 5S RNA. A disruption in the hydrophobic core of the sixth finger in p43 was identified as the probable origin of the observed thermodynamic differences. A software package, NvAsn, was written to assist in the assignment of NOEs in the spectra of the hERR2 DNA complex. The program incorporates recently developed automatic NOESY assignment algorithms into the visualization package NMRView. NvAsn provides powerful bookkeeping and model-based NOE filtering tools for spectra based, high-throughput structure determination.

Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Epigenetics: The New Molecular and Medical Genetics, Second Edition, provides a comprehensive analysis of epigenetics, from basic biology, to clinical application. Epigenetics is considered by many to be the new genetics in that many biological phenomena are controlled, not through gene mutations, but rather through reversible and heritable epigenetic processes. These epigenetic processes range from DNA methylation to prions. The biological processes impacted by epigenetics are vast and encompass effects in lower organisms and humans that include tissue and organ regeneration, X-chromosome inactivation, stem cell differentiation, genomic imprinting, and aging. The first edition of this important work received excellent reviews; the second edition continues its comprehensive coverage adding more current research and new topics based on customer and reader reviews, including new discoveries, approved therapeutics, and clinical trials. From molecular mechanisms and epigenetic technology, to discoveries in human disease and clinical epigenetics, the nature and applications of the science is presented for those with interests ranging from the fundamental basis of epigenetics, to therapeutic interventions for epigenetic-based disorders. Timely and comprehensive collection of fully up-to-date reviews on epigenetics that are organized into one volume and written by leading figures in the field Covers the latest advances in many different areas of epigenetics, ranging from basic aspects, to technologies, to clinical medicine Written at a verbal and technical level that can be understood by scientists and college students Updated to include new epigenetic discoveries, newly approved therapeutics, and clinical trials

Download or read book The Protein Binding Potential of C2H2 Zinc Finger Domains written by and published by . This book was released on 2008 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cys2-His2 (C2H2) zinc finger domains were originally identified as DNA binding domains, and uncharacterized domains are typically assumed to bind DNA. However, a growing body of evidence suggests an important and widespread role for these domains in protein binding. Over 100 C2H2 zinc finger-protein interactions have been described. This study uses common bioinformatics tools to identify sequence features that predict a DNA- or protein-binding function. Several issues, including uncertainties about the full functional capabilities of the zinc fingers, complicated these efforts. Therefore, an unbiased approach which directly examined the potential for zinc fingers to facilitate DNA or protein interactions was used to determine the full functional capabilities of the C2H2 domains in two model proteins, human OLF-1/EBF associated zinc finger (OAZ) protein and Zif268. OAZ contains 30 zinc fingers in six clusters, some of which have been previously indicated in DNA or protein interactions. Zif268 is a well-known DNA binding protein with three C2H2 domains. DNA binding was assessed using a target site selection (CAST) assay, and protein binding was assessed using a yeast two-hybrid assay. Results indicate that clusters known to bind DNA could facilitate specific protein interactions, but clusters known to bind protein did not facilitate specific DNA interactions, indicating that DNA binding is a more restricted function of zinc fingers than has previously beenrecognized. These results also suggest that the role of C2H2 zinc finger domains in protein interactions has probably been underestimated. The implication of these findings for the prediction of zinc finger function is discussed.
