TranscriptomicsBudding yeast RNA polymerase II CTD phosphorylation and transcription termination factor localization
Whole genome analysis of total RNA pol II, Ser2-, Ser5- and Ser7-phosphorylated RNA pol II, in WT and mutants of the C-terminal domain (CTD) kinases Ctk1 and Kin28, and localization of the termination factors Pcf11, Nrd1 and Rat1. ChIP-chip using ligation-mediated PCR-amplified material hybridized t...

GenomicsTyrosine phosphorylation of RNA Polymerase II CTD is associated with antisense promoter transcription and active enhancers in mammalian cells
In mammals, the carboxy-terminal domain (CTD) of RNA polymerase (Pol) II consists of 52 conserved heptapeptide repeats containing the consensus sequence Tyr1-Ser2-Pro3-Thr4-Ser5-Pro6-Ser7. Post-translational modifications of the CTD coordinate the transcription cycle and various steps of mRNA matura...

TranscriptomicsHDACs and Phosphorylated Pol II CTD recruit Spt6 for cotranscriptional histone reassembly
Spt6 is a multifunctional histone chaperone involved in the maintenance of chromatin structure during elongation by RNA polymerase II (Pol II). Spt6 has a tandem SH2 (tSH2) domain within its C-terminus that recognizes Pol II CTD peptides phosphorylated on Ser2, Ser5 or Try1 in vitro. Deleting the tS...

TranscriptomicsChIP-chip by array of yeast JTY1, SHY546, BY4743, and Bur1 strains to investigate genome-wide patterns of RNA Polymerase II CTD Phosphorylation
Chromatin Immunoprecipitation in JTY1, SHY546, BY4743, and Bur1as strains using antibodies against RNA Pol II (RPB3) and its 3 phosphorylation states Ser2-P, Ser5-P, and Ser7-P, with and without inhibition with small molecule inhibitors.

TranscriptomicsCTD tyrosine phosphorylation impairs termination factor recruitment to transcribing RNA polymerase II
ChIP-chip was performed to identify the genomic binding locations for the termination factors Nrd1, and Rtt103, and for RNA polymerase (Pol) II phosphorylated at the tyrosine 1 and threonine 4 position of its C-terminal domain (CTD). In different phases of the transcription cycle, Pol II recruits di...

GenomicsThreonine-4 of Mammalian RNA Polymerase II CTD is Targeted by Polo-like Kinase-3 and Required for Transcriptional Elongation
Eukaryotic RNA polymerase II (Pol II) has evolved an array of heptad repeats with the consensus sequence Tyr1-Ser2-Pro3-Thr4-Ser5-Pro6-Ser7 at the carboxy-terminal domain (CTD) of the large subunit (Rpb1). Differential phosphorylation of Ser2, Ser5, and Ser7 in the 5M-bM-^@M-^Y and 3M-bM-^@M-^Y regi...

TranscriptomicsChIP-chip by array of yeast to determine genome-wide occupancy profiles for RNA polymerase (Pol) II, its phosphorylated forms, and transcription factors
To investigate the chromatin transcription cycle, we determined genome-wide occupancy profiles for RNA polymerase (Pol) II, its phosphorylated forms, and transcription factors in growing yeast. ChIP-chip was performed to identify the genomic binding locations for Rpb3, TFIIB, Tfg1, Kin28, Cet1, Spt4...

TranscriptomicsCtk1 + CTD mutants
Transcription termination in Saccharomyces cerevisiae can be performed by at least two distinct pathways and is directed by the phosphorylation status of the carboxy-terminal domain (CTD) of RNA polymerase II (Pol II). Late termination of mRNAs is performed by the CPF/CF complex and requires CTD-Ser...

TranscriptomicsPostrecruitment Regulation of RNA Pol II Directs Rapid Signaling Responses at the Promoters of Estrogen Target Genes
Under current models for signal-dependent transcription in eukaryotes, DNA-binding activator proteins regulate the recruitment of RNA polymerase II (Pol II) to a set of target promoters. Yet, recent studies, as well as our results herein, show that Pol II is widely distributed (i.e., "preloaded") a...

GenomicsPol II chromatin immunoprecipitation in S. cerevisiae
In Saccharomyces cerevisiae short non-coding RNA (ncRNA) generated by RNA Polymerase II (Pol II) are terminated by the NRD complex consisting of Nrd1, Nab3 and Sen1. We now show that Pcf11, a component of the cleavage and polyadenylation complex (CPAC), is generally required for NRD-dependent transc...
