Impairing the production of ribosomal RNA activates mammalian target of rapamycin complex 1 signalling and downstream translation factors [PDF]

, 2014
Ribosome biogenesis is a key process for maintaining protein synthetic capacity in dividing or growing cells, and requires coordinated production of ribosomal proteins and ribosomal RNA (rRNA), including the processing of the latter.

FIERY1 promotes microRNA accumulation by suppressing rRNA-derived small interfering RNAs in Arabidopsis

Nature Communications, 2019
Arabidopsis AGO1 binds both microRNA (miRNA) and endogenous small interfering RNA (siRNA). Here the authors show that 5′−3′ RNA degradation suppresses siRNA biogenesis from ribosomal RNA to prevent overloading of AGO1 with ribosomal siRNA and maintain ...

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 ...

Recent Advances on the Structure and Function of RNA Acetyltransferase Kre33/NAT10

Cells, 2019
Ribosome biogenesis is one of the most energy demanding processes in the cell. In eukaryotes, the main steps of this process occur in the nucleolus and include pre-ribosomal RNA (pre-rRNA) processing, post-transcriptional modifications, and assembly of ...

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.

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 ...

Analysis of Nucleolar Protein Dynamics Reveals the Nuclear Degradation of Ribosomal Proteins [PDF]

, 2007
Background: The nucleolus is a subnuclear organelle in which rRNAs are transcribed, processed, and assembled with ribosomal proteins into ribosome subunits.

Fitness advantages conferred by the L20-interacting RNA cis -regulator of ribosomal protein synthesis in Bacillus subtilis [PDF]

, 2020
In many bacteria, ribosomal proteins autogenously repress their own expression by interacting with RNA structures typically located in the 5′′-UTRs of their mRNA transcripts.

Loss of m1acp3Ψ Ribosomal RNA Modification Is a Major Feature of Cancer

Cell Reports, 2020
Summary: The ribosome is an RNA-protein complex that is essential for translation in all domains of life. The structural and catalytic core of the ribosome is its ribosomal RNA (rRNA).
