Genome-wide analysis of factors affecting transcription elongation and DNA repair: a new role for PAF and Ccr4-not in transcription-coupled repair
(Public Library of Science, 2009)
RNA polymerases frequently deal with a number of obstacles during transcription elongation that need to be removed for transcription resumption. One important type of hindrance consists of DNA lesions, which are removed ...

Protein interactions within the Set1 complex and their roles in the regulation of histone 3 lysine 4 methylation
(Elsevier, 2006)
Set1 is the catalytic subunit and the central component of the evolutionarily conserved Set1 complex (Set1C) that methylates histone 3 lysine 4 (H3K4). Here we have determined protein/protein interactions within the complex ...

A gene-specific requirement for FACT during transcription is related to the chromatin organization of the transcribed region
(2006)
The FACT complex stimulates transcription elongation on nucleosomal templates. In vivo experiments also involve FACT in the reassembly of nucleosomes traversed by RNA polymerase II. Since several features of chromatin ...

Recruitment of a chromatin remodelling complex by the Hog1 MAP kinase to stress genes
(EMBO Press, 2009)
For efficient transcription, RNA PolII must overcome the presence of nucleosomes. The p38-related MAPK Hog1 is an important regulator of transcription upon osmostress in yeast and thereby it is involved in initiation and ...

Hpr1 is preferentially required for transcription of either long or G+C-rich DNA sequences in Saccharomyces cerevisiae
(American Society for Microbiology, 2001)
Hpr1 forms, together with Tho2, Mft1, and Thp2, the THO complex, which controls transcription elongation and genome stability in Saccharomyces cerevisiae. Mutations in genes encoding the THO complex confer strong trans ...

Regulon-Specific Control of Transcription Elongation across the Yeast Genome
(Public Library of Science, 2009)
Transcription elongation by RNA polymerase II was often considered an invariant non-regulated process. However, genome-wide studies have shown that transcriptional pausing during elongation is a frequent phenomenon in ...

Yeast Genetic Analysis Reveals the Involvement of Chromatin Reassembly Factors in Repressing HIV-1 Basal Transcription
(Public Library of Science, 2009)
Rebound of HIV viremia after interruption of anti-retroviral therapy is due to the small population of CD4+ T cells that remain latently infected. HIV-1 transcription is the main process controlling post-integration latency. ...
