AbstractThe β and β′ subunits of the RNA polymerase (RNAP) are large proteins with complex multi‐domain architectures that include several insertional domains. Here, we analyze the domain organizations of RNAP‐β and RNAP‐β′ using sequence, experimentally determined structures and AlphaFold structure predictions.

S.203-220RNA-DNA interactions can serve as a signal that triggers de novo DNA methylation in plants. As yet, this RNA-directed DNA methylation mechanism merely targets transgenes, but it appears likely that methylation of some endogenous sequences is ...

Repair of neuronal DNA damage in Alzheimer's disease by KCL‐286. (A) Amyloid‐β oligomers and plaques impair neuronal DNA repair pathways, leading to DNA double‐strand breaks and glial activation. (B) KCL‐286 activates RARβ/RXR signalling via retinoic acid response elements (RAREs), associated with increased BRCA1 expression, enhanced DNA repair and ...

Ionomycin suppresses cancer cell growth by disrupting mitochondrial transcription
In this study, we identify a new function for the selective Ca2+ ionophore, ionomycin, as an inhibitor of mitochondrial transcription. Both total and nascent RNA analyses revealed that ionomycin treatment reduces the transcription of mitochondrial genes.

Accurate and noninvasive prostate cancer detection using plasma‐derived extracellular vesicle RNA
Plasma extracellular vesicles were captured with WGA‐conjugated magnetic beads and profiled for RNA biomarkers. A three‐RNA panel (NM_024955, NR_047469, and NR_002564) distinguished prostate cancer from healthy controls and benign prostatic hyperplasia, supporting a simple, noninvasive approach to improve prostate cancer detection.

Identification of (20R)‐protopanaxadiol from Panax ginseng as a novel anti‐SARS‐CoV‐2 compound
We established a noninfectious BAC‐based SARS‐CoV‐2 replicon that enables antiviral screening under BSL‐2 conditions. Using this platform, we screened 373 food‐derived compounds and identified (20R)‐protopanaxadiol from Panax ginseng as a novel inhibitor of SARS‐CoV‐2 RNA replication, highlighting the value of safe replicon systems for antiviral ...

A yeast two-hybrid screen of a Jurkat (T cell) derived cDNA library, using SATB1 (a matrix attachment region binding protein) as the bait, yielded four independent isolates of a novel variant of the DNA directed RNA polymerase II, subunit 11 (RPB11). Absence of lysine-17 from the amino terminus of this variant cannot be explained by alternative mRNA ...

The molecular basis of nucleotide recognition for T7 DNA polymerase [PDF]
textDNA replication demands extraordinary specificity and efficiency of catalysis from a DNA polymerase. Previous studies on several DNA polymerases suggested that a rate-limiting conformational change preceding chemistry accounts for the high ...
