Abstract

The upstream binding transcription factor (UBTF, also called UBF) is thought to function exclusively in RNA polymerase I (Pol I)-specific transcription of the ribosomal genes. We recently reported in Sanij et al. (2014) [1] that the two isoforms of UBF (UBF1/2) are enriched at Pol II-transcribed genes throughout the mouse and human genomes. By using chromatin immunoprecipitation coupled with deep sequencing (ChIP-seq) of UBF1/2, Pol I, Pol II, H3K9me3, H3K4me4, H3K9ac and H4 hyperacetylation, we reported a correlation of UBF1/2 binding with enrichments in Pol II and markers of active chromatin. In addition, we examined a functional role for UBF1/2 in mediating Pol II transcription by performing expression array analysis in control and UBF1/2 depleted NIH3T3 cells. Our data demonstrate that UBF1/2 bind highly active Pol II-transcribed genes and mediate their expression without recruiting Pol I. Furthermore, we reported ChIP-sequencing analysis of UBF1/2 in immortalized human epithelial cells and their isogenically matched transformed counterparts. Here we report the experimental design and the description of the ChIP-sequencing and microarray expression datasets uploaded to NCBI Sequence Research Archive (SRA) and Gene Expression Omnibus (GEO).
