    A novel SH2 recognition mechanism recruits Spt6 to the doubly phosphorylated RNA polymerase II linker at sites of transcription

    Matthew A Sdano et al.
    The tandem SH2 domains of Spt6 use novel mechanisms to bind unexpected phosphorylated serine and threonine residues in the RNA polymerase II linker to recruit Spt6 to sites of transcription and maintain repressive chromatin.

    Tyrosine phosphorylation of RNA polymerase II CTD is associated with antisense promoter transcription and active enhancers in mammalian cells

    Nicolas Descostes et al.
    Genome-wide analysis reveals novel functions for a post-translational modification to the carboxy-terminal domain (CTD) of RNA Polymerase II in mammals.

    Requirements for RNA polymerase II preinitiation complex formation in vivo

    Natalia Petrenko et al.
    The requirements for preinitiation complex formation/stability and transcription by RNA polymerase II in yeast cells are different from those in vitro, thereby altering the current view of basal transcription.

    Live-cell single particle imaging reveals the role of RNA polymerase II in histone H2A.Z eviction

    Anand Ranjan et al.
    Histone variant H2A.Z is deposited near transcription start sites by the chromatin remodeler SWR1 and seems to be removed by RNA polymerase II at an early stage of transcription elongation.

    Methylation of RNA polymerase II non-consensus Lysine residues marks early transcription in mammalian cells

    João D Dias et al.
    Lysine mono- and di-methylation are two novel post-translational modifications of RNA polymerase II, which are enriched at promoters of active genes, precede lysine acetylation and mark early stages of transcription.

    Complete dissection of transcription elongation reveals slow translocation of RNA polymerase II in a linear ratchet mechanism

    Manchuta Dangkulwanich et al.
    Quantification of all the major on- and off-pathway kinetic parameters in the transcription elongation cycle reveals that RNA polymerase II translocates slowly in a linear, non-branched Brownian ratchet mechanism.

    RNA Polymerase II cluster dynamics predict mRNA output in living cells

    Won-Ki Cho et al.
    Quantitative super resolution imaging, in live mammalian cells, reveals a direct relationship between protein clustering dynamics and the number of mRNA transcribed at an endogenous gene locus.

    HIV Tat controls RNA Polymerase II and the epigenetic landscape to transcriptionally reprogram target immune cells

    Jonathan E Reeder et al.
    Tat uses unexpected regulatory mechanisms to reprogram target immune cells to promote viral replication and rewire pathways beneficial for HIV.

    The nucleosomal barrier to promoter escape by RNA polymerase II is overcome by the chromatin remodeler Chd1

    Peter J Skene et al.
    The ATP-dependent chromatin remodeler Chd1 controls nucleosome turnover to allow RNA Polymerase to transcribe in vivo.

    CDK9-dependent RNA polymerase II pausing controls transcription initiation

    Saskia Gressel et al.
    CDK9 inhibition in human cells uncovers that Pol II pause duration regulates the frequency of productive transcription initiation.
