Defects in SPT16 or POB3 (yFACT) in Saccharomyces cerevisiae cause dependence on the Hir/Hpc pathway: polymerase passage may degrade chromatin structureTim Formosa
Department of Biochemistry, University of Utah School of Medicine, Salt Lake City, Utah 84132, USA
Genetics 162:1557-71. 2002..Mutations that impair the reassembly activity cause chromatin to accumulate in an abnormally disrupted state, imposing a requirement for a nucleosome reassembly function that we propose is provided by Hir/Hpc proteins...
FACT and the reorganized nucleosomeTim Formosa
University of Utah School of Medicine, Department of Biochemistry, 15 N Medical Drive East RM 4100, Salt Lake City, UT 84112 5650, USA
Mol Biosyst 4:1085-93. 2008..quot; The structures of two domains of FACT have been determined and they reveal multiple potential interaction sites. Roles for these binding sites in FACT function and regulation are discussed...
Avoiding a fatal attraction: properties of nucleosomes and a histone chaperone revealed under physiological conditionsTim Formosa
Department of Biochemistry, University of Utah School of Medicine, 15 North Medical Drive East, Salt Lake City, UT 84112, USA
Mol Cell 37:747-8. 2010....
The structure of the yFACT Pob3-M domain, its interaction with the DNA replication factor RPA, and a potential role in nucleosome depositionAndrew P VanDemark
Department of Biochemistry, University of Utah School of Medicine, Salt Lake City, 84132, USA
Mol Cell 22:363-74. 2006..These results support the model that the FACT family has an essential role in constructing nucleosomes during DNA replication, and suggest that RPA contributes to this process...
Multiple Nhp6 molecules are required to recruit Spt16-Pob3 to form yFACT complexes and to reorganize nucleosomesSusan Ruone
University of Utah School of Medicine, Department of Biochemistry, Salt Lake City, Utah 84132, USA
J Biol Chem 278:45288-95. 2003..These results suggest that Nhp6 and the related high mobility group B proteins may have a general role in promoting rearrangements of chromatin by initiating the destabilization of core nucleosomal structure...
Opposing roles for Set2 and yFACT in regulating TBP binding at promotersDebabrata Biswas
Department of Pathology, University of Utah Health Sciences Center, Salt Lake City, 84112, USA
EMBO J 25:4479-89. 2006..These synthetic defects are suppressed by set2, demonstrating that yFACT and Set2 oppose one another during transcriptional initiation at a step involving DNA binding by TBP and TFIIA...
Structural and functional analysis of the Spt16p N-terminal domain reveals overlapping roles of yFACT subunitsAndrew P VanDemark
Department of Biochemistry, University of Utah School of Medicine, Salt Lake City, Utah 84112, USA
J Biol Chem 283:5058-68. 2008..The docking domain of H2A is identified as an important participant in maintaining stability during yFACT-mediated nucleosome reorganization, suggesting new models for the mechanism of this activity...
The yeast FACT complex has a role in transcriptional initiationDebabrata Biswas
Department of Pathology, University of Utah Health Sciences Center, 30 North 1900 East, Salt Lake City, Utah 84132 2501, USA
Mol Cell Biol 25:5812-22. 2005..Thus, yFACT functions in establishing transcription initiation complexes in addition to the previously described role in elongation...
Structural features of nucleosomes reorganized by yeast FACT and its HMG box component, Nhp6Alison R Rhoades
Department of Biochemistry, University of Utah School of Medicine, Salt Lake City, Utah 84132, USA
Mol Cell Biol 24:3907-17. 2004....
yFACT induces global accessibility of nucleosomal DNA without H2A-H2B displacementHua Xin
Department of Biochemistry, University of Utah School of Medicine, Salt Lake City, 84112, USA
Mol Cell 35:365-76. 2009..We propose that yFACT promotes a reversible transition between two nucleosomal forms, and that this activity contributes to the establishment and maintenance of the chromatin barrier as well as to overcoming it...
A role for Chd1 and Set2 in negatively regulating DNA replication in Saccharomyces cerevisiaeDebabrata Biswas
Department of Pathology, University of Utah Health Sciences Center, Salt Lake City, Utah 84112, USA
Genetics 178:649-59. 2008..The pob3 defect in S-phase progression is suppressed by set2 or chd1 mutations, suggesting that Set2 and Chd1 have specific roles in negatively regulating DNA replication...
blm3-1 is an allele of UBP3, a ubiquitin protease that appears to act during transcription of damaged DNAShannon McCullock
University of Utah School of Medicine, Department of Biochemistry, 15 N Medical Drive East RM 4100, Salt Lake City, UT 84112 5640, USA
J Mol Biol 363:660-72. 2006....
Structure of a Blm10 complex reveals common mechanisms for proteasome binding and gate openingKianoush Sadre-Bazzaz
Department of Biochemistry, University of Utah School of Medicine, Salt Lake City, UT 84112 5650, USA
Mol Cell 37:728-35. 2010..We also demonstrate that Blm10 acts to maintain mitochondrial function. Consistent with the structural data, the C-terminal residues of Blm10 are needed for this activity...
