Cap completion and CTD kinase recruitment govern the initiation-elongation transition of RNA polymerase II

ABSTRACT: After transcription initiation, RNA polymerase (Pol) II escapes from the promoter and recruits elongation factors. Here we used chromatin immunoprecipitation (ChIP) to elucidate the general initiation-elongation transition of Pol II in yeast. We extended our ChIP-chip occupancy profiling to capping enzymes and the cap-binding complex (CBC). We found that the first two capping enzymes, Cet1 and Ceg1, are recruited near the TSS, whereas the third enzyme, the methyltransferase Abd1, is recruited about 110 nt downstream of the TSS, and CBC is recruited further downstream. ChIP was performed using TAP-tagged S. cerevisiae strains (see protocols).

Project description:We mapped the genome-wide binding of the flagellar regulators FlhD, FlhC, and FliA in FLAG-tagged derivatives of E. coli K-12 MG1655 using ChIP coupled with deep sequencing (ChIP-seq). We identify new binding sites for each factor.

Salmonella 14028s AraC ChIP-Seq

Project description:We mapped the genome-wide binding of C-terminally FLAG-tagged AraC in S. enterica subsp. enterica serovar Typhimurium strain 14028s using ChIP coupled with deep sequencing (ChIP-seq). We identified five putative target loci for AraC: upstream of araB/araC, araE, araJ, STM14_0178, and within sseD.

ChIP-seq of sigma 70 in wild-type and hns mutant Escherichia coli K-12 MG1655

Project description:We mapped the genome-wide binding of sigma 70 in E. coli K-12 MG1655 and an hns mutant that is otherwise isogenic using ChIP coupled with deep sequencing (ChIP-seq). We show that intragenic binding of sigma 70 is increased in the hns mutant.

ChIP-seq of MG1655 wt, MG1655 ΔphoB, MG1655 Δhns, MG1655 ΔphoB+Δhns and MG1655 PhoB-FLAG strains grown in MOPS media with either low phosphate (0.2 mM) or high phosphate (1.32 mM)

Project description:We used ChIP-seq to map the binding of of C-terminally FLAG3-tagged PhoB to the Escherichia coli K-12 genome during growth in MOPS minimal media with low phosphate or high phosphate (0.2 mM or 1.32 mM, respectively). As a control, we performed ChIP-seq in an untagged strain. We also used ChIP-seq to map Sigma 70 (associates with initiating RNA polymerase) binding across the E. coli K-12 genome in wild-type, ΔphoB, Δhns, and Δhns ΔphoB strains grown in low phosphate medium to determine whether PhoB modulates recruitment of RNA polymerase to promoters and whether this is modulated by H-NS.

Project description:ChIP-seq was performed to map the association of SPA-tagged DnaA across the Escherichia coli MG1655 chromosome during exponential phase growth in LB. As a control to remove background, ChIP-Seq was also performed on SPA-tagged AcpS, a protein that is not known to bind DNA.

ChIP-seq of Escherichia coli RpoS during stationary phase

Project description:To determine sites where RpoS binds (and hence likely plays a direct role in transcription), we used ChIP-seq to map the association of RpoS across the Escherichia coli chromosome during stationary phase growth in minimal medium. To facilitate ChIP, RpoS was C-terminally SPA-tagged at its native locus.
