Genome-wide off-rates reveal how DNA binding dynamics shape transcription factor function.
Title: Genome-wide off-rates reveal how DNA binding dynamics shape transcription factor function.
Abf1, Reb1, and Tbf1 control ribosome biogenesis gene expression in budding yeast.
Title: Abf1 and other general regulatory factors control ribosome biogenesis gene expression in budding yeast.
We present evidence that Abf1 recruitment upon nutritional stress, also observed for representative ribosome biogenesis genes, favours RPG transcriptional rescue upon nutrient replenishment, thus pointing to nutrient-regulated Abf1 dynamics at promoters as a novel mechanism in ribosome biogenesis control.
Title: Promoter architecture and transcriptional regulation of Abf1-dependent ribosomal protein genes in Saccharomyces cerevisiae.
It was found that ABF1, FKH2, and REB1 overexpression decreased the growth of strains in a prion-dependent manner and, thus, might influence [PSI;(+)] prion toxicity.
Title: [Identification of new genes that affect [PSI^(+)] prion toxicity in Saccharomyces cerevisiae yeast].
Results show that Abf1 contributes to local regions of chromatin structure by acting at both strong and weak binding sites, at proximal promoter regions and at sites farther upstream, over a very large fraction of the yeast genome.
Title: Extensive role of the general regulatory factors, Abf1 and Rap1, in determining genome-wide chromatin structure in budding yeast.
Data suggest an involvement of Abf1p transcription factor in intergenomic signaling.
Title: Multiple pathways of mitochondrial-nuclear communication in yeast: intergenomic signaling involves ABF1 and affects a different set of genes than retrograde regulation.
Mutation of the I silencer ABF1-binding site at the HMLalpha locus caused loss of ABF1 binding, which resulted in a domain of reduced global genome nucleotide excision repair efficiency on one side of the ABF1-binding site
Title: ABF1-binding sites promote efficient global genome nucleotide excision repair.
The present study revealed numerous loci previously unknown to be under Abf1 control, and it yielded evidence for the protein's variable DNA binding pattern during mitotic growth and meiotic development.
Title: Genome-wide expression profiling, in vivo DNA binding analysis, and probabilistic motif prediction reveal novel Abf1 target genes during fermentation, respiration, and sporulation in yeast.
DNA sequences were found that are bound by ABF1 with nearly two-magnitude higher affinity as compared to the hitherto accepted ABF1 consensus sequence.
Title: In vitro selection of DNA binding sites for ABF1 protein from Saccharomyces cerevisiae.
Results compare the ability of RAP1 and ABF1 to create a region of open chromatin near and to contribute to activated transcription at promoters.
