Topoisomerase IIα promotes activation of RNA polymerase I transcription by facilitating pre-initiation complex formation [PDF]

, 2013
Type II DNA topoisomerases catalyse DNA double-strand cleavage, passage and re-ligation to effect topological changes. There is considerable interest in elucidating topoisomerase II roles, particularly as these proteins are targets for anti-cancer drugs.

RNA polymerase I mutant affects ribosomal RNA processing and ribosomal DNA stability

RNA Biology
Transcription is a major contributor to genomic instability. The ribosomal RNA (rDNA) gene locus consists of a head-to-tail repeat of the most actively transcribed genes in the genome.

Ribosomal history reveals origins of modern protein synthesis. [PDF]

PLoS ONE, 2012
The origin and evolution of the ribosome is central to our understanding of the cellular world. Most hypotheses posit that the ribosome originated in the peptidyl transferase center of the large ribosomal subunit.

An HflX-type GTPase from Sulfolobus solfataricus binds to the 50S ribosomal subunit in all nucleotide-bound states [PDF]

, 2011
HflX GTPases are found in all three domains of life, Bacteria, Archaea, and Eukaryotes. HflX from Escherichia coli has been shown to bind to the 50S ribosomal subunit in a nucleotide-dependent manner and this interaction strongly stimulates its GTPase ...

Yeast Rrp8p, a novel methyltransferase responsible for m1A 645 base modification of 25S rRNA [PDF]

, 2012
Ribosomal RNA undergoes various modifications to optimize ribosomal structure and expand the topological potential of RNA. The most common nucleotide modifications in ribosomal RNA (rRNA) are pseudouridylations and 2'-O methylations (Nm), performed by H ...

Efficient depletion of ribosomal RNA for RNA sequencing in planarians

BMC Genomics, 2019
Background The astounding regenerative abilities of planarian flatworms prompt steadily growing interest in examining their molecular foundation. Planarian regeneration was found to require hundreds of genes and is hence a complex process.
