In Silico Analysis of Honey Bee Peptides as Potential Inhibitors of Capripoxvirus DNA-Directed RNA Polymerase

open access: yesAnimals, 2023
The genus Capripoxvirus belongs to the Poxviridae family. The sheeppox, goatpox, and lumpy skin disease viruses are three species of this genus with 96% identity in their genomes.

Metal A and metal B sites of nuclear RNA polymerases Pol IV and Pol V are required for siRNA-dependent DNA methylation and gene silencing. [PDF]

open access: yesPLoS ONE, 2009
Plants are unique among eukaryotes in having five multi-subunit nuclear RNA polymerases: the ubiquitous RNA polymerases I, II and III plus two plant-specific activities, nuclear RNA polymerases IV and V (previously known as Polymerases IVa and IVb).

Dynamic regulation of ARGONAUTE4 within multiple nuclear bodies in Arabidopsis thaliana. [PDF]

open access: yesPLoS Genetics, 2008
DNA methylation directed by 24-nucleotide small RNAs involves the small RNA-binding protein ARGONAUTE4 (AGO4), and it was previously shown that AGO4 localizes to nucleolus-adjacent Cajal bodies, sites of snRNP complex maturation. Here we demonstrate that

The Rise and Fall of Billionaire siRNAs during Reproductive Development in Rice

open access: yesPlants, 2022
RNA polymerase IV-dependent siRNAs, usually 24 nt in length, function in the RNA-directed DNA methylation that is responsible for de novo methylation in plants.

New link between the RNA polymerase II-CTD and replication stress

open access: yesMolecular & Cellular Oncology, 2021
Conflicts between transcription and replication are a major source of replication stress. Our recent findings show that proper dephosphorylation of Serine 5 in the carboxy-terminal domain (CTD) of DNA-directed RNA polymerase II subunit RPB1 is needed to ...

Primer recognition by avian myeloblastosis virus RNA-directed DNA polymerase [PDF]

open access: yesJournal of Virology, 1977
Tryptophanyl-tRNA was specifically labeled at the 3' end with [3H]tryptophan and cleaved in half with RNase under denaturing conditions, and the 3' half was shown to hybridize exclusively at the 5' end of avian myeloblastosis virus RNA. The RNA-dependent DNA polymerase of avian myeloblastosis virus is capable of efficiently binding the 3' half of the ...

Production and processing of siRNA precursor transcripts from the highly repetitive maize genome. [PDF]

open access: yesPLoS Genetics, 2009
Mutations affecting the maintenance of heritable epigenetic states in maize identify multiple RNA-directed DNA methylation (RdDM) factors including RMR1, a novel member of a plant-specific clade of Snf2-related proteins.

FVE promotes RNA‐directed DNA methylation by facilitating the association of RNA polymerase V with chromatin [PDF]

open access: bronzeThe Plant Journal, 2021
SummaryAssociation of RNA polymerase V (Pol V) with chromatin is a critical step for RNA‐ directed DNA methylation (RdDM) in plants. Although the methylated DNA‐binding proteins SUVH2 and SUVH9 and the chromatin remodeler‐containing complex DRD1‐DMS3‐RDM1 are known to be required for the association of Pol V with chromatin, the molecular mechanisms ...

The ability to form homodimers is essential for RDM1 to function in RNA-directed DNA methylation. [PDF]

open access: yesPLoS ONE, 2014
RDM1 (RNA-DIRECTED DNA METHYLATION1) is a small plant-specific protein required for RNA-directed DNA methylation (RdDM). RDM1 interacts with RNA polymerase II (Pol II), ARGONAUTE4 (AGO4), and the de novo DNA methyltransferase DOMAINS REARRANGED ...
