Altered hematopoiesis in mice lacking DNA polymerase mu is due to inefficient double-strand break repair. [PDF]

PLoS Genetics, 2009
Polymerase micro (Polmicro) is an error-prone, DNA-directed DNA polymerase that participates in non-homologous end-joining (NHEJ) repair. In vivo, Polmicro deficiency results in impaired Vkappa-Jkappa recombination and altered somatic hypermutation and ...

RNase-like domain in DNA-directed RNA polymerase II. [PDF]

Proceedings of the National Academy of Sciences, 1991
DNA-directed RNA polymerase is responsible for gene expression. Despite its importance, many details of its function and higher-order structure still remain unknown. We report here a local sequence similarity between the second largest subunit of RNA polymerase II and bacterial RNases Ba (barnase), Bi, and St. The most remarkable similarity is that the

RNA polymerase II stalling promotes nucleosome occlusion and pTEFb recruitment to drive immortalization by Epstein-Barr virus [PDF]

, 2011
Epstein-Barr virus (EBV) immortalizes resting B-cells and is a key etiologic agent in the development of numerous cancers. The essential EBV-encoded protein EBNA 2 activates the viral C promoter (Cp) producing a message of ~120 kb that is differentially ...

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 ...

Antibodies to the DNA-directed RNA polymerase II subunit RPB1 occur with highest frequency in centenarians [PDF]

Immunity & Ageing, 2016
Recently, phage display technology has made it possible to define the circulating repertoire of humoral immunity. This study was designed to define the circulating antibodies specific to centenarians.We used a phage-displayed combinatorial peptide library to screen for peptides (YSATLRY and YSPTLFY) that preferentially react with the IgG fraction of ...

RNA-directed DNA methylation involves co-transcriptional small-RNA-guided slicing of polymerase V transcripts in Arabidopsis. [PDF]

, 2018
Small RNAs regulate chromatin modifications such as DNA methylation and gene silencing across eukaryotic genomes. In plants, RNA-directed DNA methylation (RdDM) requires 24-nucleotide small interfering RNAs (siRNAs) that bind to ARGONAUTE 4 (AGO4) and ...
