HMG-boxes, ribosomopathies and neurodegenerative disease

Frontiers in Genetics, 2023
The UBTF E210K neuroregression syndrome is a predominantly neurological disorder caused by recurrent de novo dominant variants in Upstream Binding Factor, that is, essential for transcription of the ribosomal RNA genes. This unusual form of ribosomopathy

Cross-site comparison of ribosomal depletion kits for Illumina RNAseq library construction

BMC Genomics, 2018
Background Ribosomal RNA (rRNA) comprises at least 90% of total RNA extracted from mammalian tissue or cell line samples. Informative transcriptional profiling using massively parallel sequencing technologies requires either enrichment of mature poly ...

Ribosomal RNA regulates chromosome clustering during mitosis

Cell Discovery, 2022
Noncoding RNAs are known to associate with mitotic chromosomes, but the identities and functions of chromosome-associated RNAs in mitosis remain elusive. Here, we show that rRNA species associate with condensed chromosomes during mitosis.

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.

RNA G-quadruplex structures control ribosomal protein production

Scientific Reports, 2021
Four-stranded G-quadruplex (G4) structures form from guanine-rich tracts, but the extent of their formation in cellular RNA and details of their role in RNA biology remain poorly defined.

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.

Dynamic relationships between ribosomal conformational and RNA positional changes during ribosomal translocation

Heliyon, 2016
Ribosomal translocation catalyzed by EF-G hydrolyzing GTP entails multiple conformational changes of ribosome and positional changes of tRNAs and mRNA in the ribosome.

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.

Selection of Peptides Targeting Helix 31 of Bacterial 16S Ribosomal RNA by Screening M13 Phage-Display Libraries

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
