Molecules, 2011 Ribosomal RNA is the catalytic portion of ribosomes, and undergoes a variety of conformational changes during translation. Structural changes in ribosomal RNA can be facilitated by the presence of modified nucleotides. Helix 31 of bacterial 16S ribosomal

The ribosome assembly gene network is controlled by the feedback regulation of transcription elongation [PDF]
, 2017 Ribosome assembly requires the concerted expression of hundreds of genes, which are transcribed by all three nuclear RNA polymerases. Transcription elongation involves dynamic interactions between RNA polymerases and chromatin.

The human methyltransferase ZCCHC4 catalyses N6-methyladenosine modification of 28S ribosomal RNA
Nucleic Acids Research, 2019 RNA methylations are essential both for RNA structure and function, and are introduced by a number of distinct methyltransferases (MTases). In recent years, N6-methyladenosine (m6A) modification of eukaryotic mRNA has been subject to intense studies, and

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.

Structural basis of ribosomal RNA transcription regulation
Nature Communications, 2021 Ribosomal RNA (rRNA) expression is regulated at the initiation stage of RNA synthesis. Here, the authors report cryo-EM structures of E. coli RNA polymerase and rRNA promoter complex with DksA/ppGpp on the way to open complex formation, identifying key ...

Ribosomes and ribosomal RNA as chaperones for folding of proteins
Folding and Design, 1997 Provocative recent reports indicate that the large subunits of either prokaryotic or eukaryotic ribosomes have the capacity to promote refolding of denatured enzymes.Salt-washed Escherichia coli ribosomes are shown to promote refolding of denatured rhodanese.

Hepatitis C virus 3'UTR regulates viral translation through direct interactions with the host translation machinery. [PDF]
, 2013 The 3' untranslated region (3'UTR) of hepatitis C virus (HCV) messenger RNA stimulates viral translation by an undetermined mechanism. We identified a high affinity interaction, conserved among different HCV genotypes, between the HCV 3'UTR and the host ...

Small Non-Coding RNAs Derived from Eukaryotic Ribosomal RNA
Non-Coding RNA, 2019 The advent of RNA-sequencing (RNA-Seq) technologies has markedly improved our knowledge and expanded the compendium of small non-coding RNAs, most of which derive from the processing of longer RNA precursors.

A working model for cytoplasmic assembly of H/ACA snoRNPs
FEBS Letters, EarlyView.Dyskerin is the component of nuclear H/ACA ribonucleoproteins (RNPs) endowed with pseudouridine synthase catalytic activity. Two isoforms of human dyskerin have been characterized: the abundant Iso1, mainly nuclear, and the shorter Iso3, mainly cytoplasmic but occasionally imported into nuclei.

Placeholder factors in ribosome biogenesis: please, pave my way
Microbial Cell, 2017 The synthesis of cytoplasmic eukaryotic ribosomes is an extraordinarily energy-demanding cellular activity that occurs progressively from the nucleolus to the cytoplasm.
