Iwr1 Protein Is Important for Preinitiation Complex Formation by All Three Nuclear RNA Polymerases in Saccharomyces cerevisiae
TLDR
Iwr1 plays an important role in preinitiation complex formation by all three nuclear RNA polymerases, including Pol III transcription, in S. cerevisiae.
Iwr 1 Protein Is Important for Preinitiation Complex Formation by All Three Nuclear RNA Polymerases in \ ( Saccharomyces
TLDR
Iwr1 Protein Is Important for Preinitiation Complex Formation by All Three Nuclear RNA Polymerases in Saccharomyces cerevisiae and plays an important role in preinitiation complex formation by all three nuclear RNA polymerases.
Novel layers of RNA polymerase III control affecting tRNA gene transcription in eukaryotes
TLDR
Models of Pol III based on cryo-electron microscopy reconstructions of distinct Pol III conformations reveal unique features distinguishing Pol III from other polymerases, related to a short transcript length and high transcription efficiency.
Cryo-EM structure of mammalian RNA polymerase II in complex with human RPAP2
TLDR
The cryo-electron microscopy structure of mammalian Pol II in complex with human RPAP2 at 2.8 Å resolution shows thatRPAP2 binds between the jaw domains of the polymerase subunits RPB1 and RPB5, which is incompatible with binding of downstream DNA during transcription.
Biogenesis of multisubunit RNA polymerases.
Rtp1p Is a Karyopherin-Like Protein Required for RNA Polymerase II Biogenesis
TLDR
Rtp1p is defined as a new component of the RNA pol II biogenesis machinery that plays roles in subunit assembly and likely in transport through the nuclear pore complex.
Rbs1, a New Protein Implicated in RNA Polymerase III Biogenesis in Yeast Saccharomyces cerevisiae
TLDR
It is demonstrated that a missense cold-sensitive mutation, rpc128-1007, in the sequence encoding the C-terminal part of the second largest Pol III subunit, C128, affects the assembly and stability of the enzyme and postulate that Rbs1 binds to the Pol III complex or subcomplex and facilitates its translocation to the nucleus.

The Yeast RNA Polymerase II-associated Factor Iwr1p Is Involved in the Basal and Regulated Transcription of Specific Genes*
TLDR
The results show that Iwr1p is a nucleocytoplasmic shuttling protein and suggest that IWR1p acts early in the formation of the pre-initiation complex by mediating the interaction of certain activators with the basal transcription apparatus.
Structure of eukaryotic RNA polymerases.
TLDR
A catalog of available structural information for Pol I, Pol II, and Pol III is provided, which showed that the active center region and core enzymes are similar to Pol II and that strong structural differences on the surfaces account for gene class-specific functions.
Structure of an RNA polymerase II–RNA inhibitor complex elucidates transcription regulation by noncoding RNAs
TLDR
The crystal structure of FC*, the central part of FC RNA, bound to Pol II indicates that A-form RNA could interact with Pol II similarly to a B-form DNA promoter, as suggested for the bacterial transcription inhibitor 6S RNA.
RNA polymerase II–TFIIB structure and mechanism of transcription initiation
TLDR
The crystal structure of the complete Pol II–B complex at 4.3 Å resolution is presented, and the results indicate the mechanism of transcription initiation, including the transition to RNA elongation.
The Protein Interaction Network of the Human Transcription Machinery Reveals a Role for the Conserved GTPase RPAP4/GPN1 and Microtubule Assembly in Nuclear Import and Biogenesis of RNA Polymerase II*
TLDR
RPAP4/GPN1 is a member of a newly discovered GTPase family that contains a unique and highly conserved GPN loop motif that is essential, in conjunction with its GTP-binding motifs, for nuclear localization of POLR2A/RPB1 in a process that also requires microtubule assembly.
Structural Basis of Transcription: RNA Polymerase II at 2.8 Ångstrom Resolution
TLDR
Structures of a 10-subunit yeast RNA polymerase II derived from two crystal forms at 2.8 and 3.1 angstrom resolution provide evidence for RNA exit in the vicinity of the carboxyl-terminal repeat domain, coupling synthesis to RNA processing by enzymes bound to this domain.
RNA‐directed DNA methylation and plant development require an IWR1‐type transcription factor
TLDR
A genetic screen designed to reveal factors that are important for RdDM in a developmental context in Arabidopsis identified DMS4, which might be a regulatory factor for several RNA polymerases, thus explaining its diverse roles in the plant.
