A model for the study of ligand binding to the ribosomal RNA helix h44. [PDF]
, 2010 Oligonucleotide models of ribosomal RNA domains are powerful tools to study the binding and molecular recognition of antibiotics that interfere with bacterial translation.

The 23S Ribosomal RNA From Pyrococcus furiosus Is Circularly Permuted
Frontiers in Microbiology, 2020 Synthesis and assembly of ribosomal components are fundamental cellular processes and generally well-conserved within the main groups of organisms. Yet, provocative variations to the general schemes exist. We have discovered an unusual processing pathway

Transcription-translation coupling: direct interactions of RNA polymerase with ribosomes and ribosomal subunits. [PDF]
, 2017 In prokaryotes, RNA polymerase and ribosomes can bind concurrently to the same RNA transcript, leading to the functional coupling of transcription and translation.

Autophagy regulates rRNA synthesis
Nucleus, 2022 Autophagy has emerged as a key regulator of cell metabolism. Recently, we have demonstrated that autophagy is involved in RNA metabolism by regulating ribosomal RNA (rRNA) synthesis.

Homoiterons and expansion in ribosomal RNAs [PDF]
FEBS Open Bio, 2015 Ribosomal RNAs in both prokaryotes and eukaryotes feature numerous repeats of three or more nucleotides with the same nucleobase (homoiterons). In prokaryotes these repeats are much more frequent in thermophile compared to mesophile or psychrophile species, and have similar frequency in both large RNAs.

Conformational switches control early maturation of the eukaryotic small ribosomal subunit
eLife, 2019 Eukaryotic ribosome biogenesis is initiated with the transcription of pre-ribosomal RNA at the 5’ external transcribed spacer, which directs the early association of assembly factors but is absent from the mature ribosome.

RNA‐guided nucleotide modification of ribosomal and non‐ribosomal RNAs in Archaea [PDF]
Molecular Microbiology, 2004 SummaryArchaea use ribonucleoprotein (RNP) machines similar to those found in the eukaryotic nucleolus to methylate ribose residues in nascent ribosomal RNA. The archaeal complex required for this 2′‐O‐ribose‐methylation consists of the C/D box sRNA guide and three proteins, the core RNA‐binding aL7a protein, the aNop56 protein and the ...

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 ...
