Chromatin immunoprecipitation to measure RNA polymerase II occupancy in fission yeast

ABSTRACT: The relative amount of RNA polymerase II (Pol II) associated with a given ORF provides an estimate for transcriptional efficiency. We therefore established a systematic approach to measure Pol II occupancy using chromatin immunoprecipitation followed by analysis on microarrays

Gene expression is controlled at multiple layers, and cells may integrate different regulatory steps for coherent production of proper protein levels. We applied various microarray-based approaches to determine key gene-expression intermediates in exponentially growing fission yeast, providing genome-wide data for translational profiles, mRNA steady-state levels, polyadenylation profiles, start-codon sequence context, mRNA half-lives, and RNA polymerase II occupancy. We uncovered widespread and ...[more]

Transcription profiling of fission yeast timecourse mcs6 mutant

Project description:The fission yeast Mcs6-Mcs2-Pmh1 complex (homologous to metazoan Cdk7-cyclin HMat1) performs dual functions: in cell cycle control, as a CDK-activating kinase; and in transcription by RNA polymerase (Pol) II, as part of TFIIH. It is unknown whether that linkage serves to coordinate gene expression with cell division. Mutants in mcs6 and pmh1 arrest with incomplete cell separation and decreased phosphorylation of the Pol II large subunit. Gene expression profiling by microarray hybridization revealed that a defined subset (~5%) of genes was repressed by Mcs6 complex impairment, whereas the majority was refractory. The repression signature included a cell-cycle cluster implicated in cytokinesis and cell separation, and overlapped with those of the cell-separation mutants sep1, sep10 and sep15 (relative to wild-type cells). The gene sep10 encodes the homolog of a protein found in metazoan Mediator-like complexes, and sep15 encodes an established component of the Mediator. In mcs6 or pmh1 mutants, sep10+, which also encodes a component of the transcriptional machinery, becomes essential for viability. Finally, mcs6+ also interacts genetically with sep1+, which encodes a forkhead transcription factor required for periodic transcription during mitosis and cell division. Thus, the Mcs6 complex (a direct activator of the cell-cycle engine) also helps govern the cell-cycle transcriptional program.
