Polymerase IV occupancy at RNA-directed DNA methylation sites requires SHH1 [PDF]
Nature, 2013 DNA methylation is an epigenetic modification that plays critical roles in gene silencing, development, and genome integrity. In Arabidopsis, DNA methylation is established by DOMAINS REARRANGED METHYLTRANSFERASE 2 (DRM2) and targeted by 24 nt small interfering RNAs (siRNAs) through a pathway termed RNA-directed DNA methylation (RdDM)1.

An RNA polymerase II- and AGO4-associated protein acts in RNA-directed DNA methylation [PDF]
Nature, 2010 DNA methylation is an important epigenetic mark in many eukaryotes. In plants, 24-nucleotide small interfering RNAs (siRNAs) bound to the effector protein, Argonaute 4 (AGO4), can direct de novo DNA methylation by the methyltransferase DRM2 (refs 2, 4-6). Here we report a new regulator of RNA-directed DNA methylation (RdDM) in Arabidopsis: RDM1.

New link between the RNA polymerase II-CTD and replication stress
Molecular & 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]
Journal 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 ...

Endogenous RNA-Directed DNA Polymerase Activity in Uninfected Chicken Embryos [PDF]
Proceedings of the National Academy of Sciences, 1972 Early chicken embryos that are either positive or negative for group-specific antigens of avian leukosis viruses contained endogenous RNA-directed DNA polymerase activity. This endogenous DNA polymerase activity was not increased after mixture of soluble DNA polymerases isolated from chicken embryos with disrupted chicken embryo cells.

DNA polymerase of reticuloendotheliosis virus: Inability to detect endogenous RNA-directed DNA synthesis [PDF]
Virology, 1975 Abstract Purified preparations of reticuloendotheliosis virus (REV) appear to lack the endogenous RNase-sensitive DNA polymerase activity present in most, if not all, avian RNA tumor viruses. Although no endogenous RNA-directed DNA polymerase could be detected in REV, we have been able to demonstrate the presence of a virion-associated DNA polymerase

Human p53 interacts with the elongating RNAPII complex and is required for the release of actinomycin D induced transcription blockage [PDF]
, 2017 The p53 tumour suppressor regulates the transcription initiation of selected genes by binding to specific DNA sequences at their promoters. Here we report a novel role of p53 in transcription elongation in human cells.

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

RNA-directed DNA polymerase from particles released by normal goose cells [PDF]
Journal of Virology, 1979 Cells from a goose embryo were shown to release particle-associated RNA-directed DNA polymerase and RNase H activities that required the presence of Nonidet P-40 for detection. The particles were not infectious and did not have endogenous DNA synthesis.
