Expression analysis of Drosophila S2R+ cells depleted of M1BP by RNAi


ABSTRACT: Microarray analysis of gene expression profiles in control and M1BP-depleted Drosophila S2R+ cells. The results of this analyses are reported in Li, J. and D.S. Gilmour (2013) The newly identified transcription factor M1BP ad GAGA factor orchestrate distinct mechanisms of transcriptional regulation on paused genes. The EMBO J, in press.

Distinct mechanisms of transcriptional pausing orchestrated by GAGA factor and M1BP, a novel transcription factor.

Thousands of genes in Drosophila have Pol II paused in the promoter proximal region. Almost half of these genes are associated with either GAGA factor (GAF) or a newly discovered factor we call M1BP. Although both factors dictate the association of Pol II at their target promoters, they are nearly mutually exclusive on the genome and mediate different mechanisms of regulation. High-resolution mapping of Pol II using permanganate-ChIP-seq indicates that pausing on M1BP genes is transient and coul  ...[more]
