Structure and mechanism of the plant RNA polymerase V
Science, 2023 In addition to the conserved RNA polymerases I to III (Pols I to III) in eukaryotes, two atypical polymerases, Pols IV and V, specifically produce noncoding RNA in the RNA-directed DNA methylation pathway in plants.

Genes & Development, 2000 Transcription control at the melting step is not yet understood. Here, band shift, cross-linking, and transcription experiments on diverse DNA probes were used with two bacterial RNA polymerase holoenzymes that differ in how they regulate melting.

Evolution of Complex RNA Polymerases: The Complete Archaeal RNA Polymerase Structure
PLoS Biology, 2009 The archaeal RNA polymerase (RNAP) shares structural similarities with eukaryotic RNAP II but requires a reduced subset of general transcription factors for promoter-dependent initiation.

Atypical DNA methylation of genes encoding cysteine-rich peptides in
BMC Plant Biology, 2012 Background In plants, transposons and non-protein-coding repeats are epigenetically silenced by CG and non-CG methylation. This pattern of methylation is mediated in part by small RNAs and two specialized RNA polymerases, termed Pol IV and Pol V, in a ...

Isolation and characterization of monoclonal antibodies directed against two subunits of rabbit poxvirus-associated, DNA-directed RNA polymerase [PDF]
Journal of Virology, 1985 A library of monoclonal antibodies directed against individual proteins of the rabbit poxvirus (RPV) virion within a complex immunogenic mixture has been generated through the use of in vivo and in vitro immunization regimens. The relative efficacies of the two procedures were compared.

Structure and RNA template requirements of Arabidopsis RNA-DEPENDENT RNA POLYMERASE 2
Proceedings of the National Academy of Sciences of the United States of America, 2021 Significance RDR2 is critical for siRNA-directed DNA methylation in Arabidopsis, functioning in physical association with DNA-dependent Pol IV to synthesize the second strands of double-stranded siRNA precursors.

Distinct transcriptional responses of RNA polymerases I, II and III to aptamers that bind TBP
Nucleic Acids Research, 2005 The TATA-binding protein (TBP) is a general factor that is involved in transcription by all three types of nuclear RNA polymerase. To delineate the roles played by the DNA-binding surface of TBP in these transcription reactions, we used a set of RNA ...

Expression, crystallization and preliminary X-ray crystallographic analysis of DNA-directed RNA polymerase subunit L fromThermococcus onnurineusNA1 [PDF]
Acta Crystallographica Section F Structural Biology Communications, 2014 RNA polymerase (RNAP) plays a crucial role in gene expression in all organisms. It is a multiprotein complex that produces primary transcript RNA. Generally, the basal transcription apparatus in archaea is simpler than the eukaryotic RNA polymerase II counterpart.
