Epitranscriptomics of Mammalian Mitochondrial Ribosomal RNA
Cells, 2020 Modified nucleotides are present in all ribosomal RNA molecules. Mitochondrial ribosomes are unique to have a set of methylated residues that includes universally conserved ones, those that could be found either in bacterial or in archaeal/eukaryotic ...

SINA: Accurate high-throughput multiple sequence alignment of ribosomal RNA genes
Bioinform., 2012 MOTIVATION In the analysis of homologous sequences, computation of multiple sequence alignments (MSAs) has become a bottleneck. This is especially troublesome for marker genes like the ribosomal RNA (rRNA) where already millions of sequences are publicly

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

Circular non-coding RNA ANRIL modulates ribosomal RNA maturation and atherosclerosis in humans
Nature Communications, 2016 Circular RNAs (circRNAs) are broadly expressed in eukaryotic cells, but their molecular mechanism in human disease remains obscure. Here we show that circular antisense non-coding RNA in the INK4 locus (circANRIL), which is transcribed at a locus of ...

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.

Two RNA-binding motifs in eIF3 direct HCV IRES-dependent translation. [PDF]
, 2013 The initiation of protein synthesis plays an essential regulatory role in human biology. At the center of the initiation pathway, the 13-subunit eukaryotic translation initiation factor 3 (eIF3) controls access of other initiation factors and mRNA to the

Control of ribosome traffic by position-dependent choice of synonymous codons [PDF]
Phys. Biol. 10 (2013) 056011, 2013 Messenger RNA encodes a sequence of amino acids by using codons. For most amino acids there are multiple synonymous codons that can encode the amino acid. The translation speed can vary from one codon to another, thus there is room for changing the ribosome speed while keeping the amino acid sequence and hence the resulting protein.

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.

Distribution of dwell times of a ribosome: effects of infidelity, kinetic proofreading and ribosome crowding [PDF]
Physical Biology, 8 (2011) 026005, 2010 Ribosome is a molecular machine that polymerizes a protein where the sequence of the amino acid residues, the monomers of the protein, is dictated by the sequence of codons (triplets of nucleotides) on a messenger RNA (mRNA) that serves as the template. The ribosome is a molecular motor that utilizes the template mRNA strand also as the track. Thus, in
