Heterochromatic siRNAs and DDM1 independently silence aberrant 5S rDNA transcripts in Arabidopsis. [PDF]
PLoS ONE, 2009 5S ribosomal RNA gene repeats are arranged in heterochromatic arrays (5S rDNA) situated near the centromeres of Arabidopsis chromosomes. The chromatin remodeling factor DDM1 is known to maintain 5S rDNA methylation patterns while silencing transcription ...

5SRNAdb: an information resource for 5S ribosomal RNAs [PDF]
Nucleic Acids Research, 2015 Ribosomal 5S RNA (5S rRNA) is the ubiquitous RNA component found in the large subunit of ribosomes in all known organisms. Due to its small size, abundance and evolutionary conservation 5S rRNA for many years now is used as a model molecule in studies on RNA structure, RNA-protein interactions and molecular phylogeny. 5SRNAdb (http://combio.pl/5srnadb/)

Characterization of a novel association between two trypanosome-specific proteins and 5S rRNA. [PDF]
PLoS ONE, 2012 P34 and P37 are two previously identified RNA binding proteins in the flagellate protozoan Trypanosoma brucei. RNA interference studies have determined that the proteins are essential and are involved in ribosome biogenesis.

RNAmmer: consistent and rapid annotation of ribosomal RNA genes [PDF]
Nucleic Acids Research, 2007 The publication of a complete genome sequence is usually accompanied by annotations of its genes. In contrast to protein coding genes, genes for ribosomal RNA (rRNA) are often poorly or inconsistently annotated.

Early evolutionary colocalization of the nuclear ribosomal 5S and 45S gene families in seed plants: evidence from the living fossil gymnosperm Ginkgo biloba [PDF]
Heredity, 2012 In seed plants, the colocalization of the 5S loci within the intergenic spacer (IGS) of the nuclear 45S tandem units is restricted to the phylogenetically derived Asteraceae family. However, fluorescent in situ hybridization (FISH) colocalization of both

Assessing Human Ribosomal DNA Variation and Its Association With Phenotypic Outcomes. [PDF]
BioessaysGenetic variation within the multi‐copy, multi‐locus ribosomal DNA (rDNA) can contribute to human complex trait variability. This variation takes the form of copy number, structural arrangement, and sequence differences. This review summarizes what is currently known about human rDNA variation, its causes, and its association with phenotypic outcomes ...

ELECTROPHORESIS, Volume 43, Issue 23-24, Page 2402-2427, December 2022., 2022 Abstract Nucleic acids are the blueprint of life. They are not only the construction plan of the single cell or higher associations of them, but also necessary for function, communication and regulation. Due to the pandemic, the attention shifted in particular to their therapeutic potential as a vaccine. As pharmaceutical oligonucleotides are unique in

Generalized structures of the 5S ribosomal RNAs [PDF]
Nucleic Acids Research, 1982 The sequences of 5S ribosomal RNAs from a wide-range of organisms have been compared. All sequences fit a generalized 5S RNA secondary structural model. Twenty-three nucleotide positions are found universally, i.e., in 5S RNAs of eukaryotes, prokaryotes, archaebacteria, chloroplasts and mitochondria.

5S ribosomal RNA database Y2K [PDF]
Nucleic Acids Research, 2000 This paper presents the updated version (Y2K) of the database of ribosomal 5S ribonucleic acids (5S rRNA) and their genes (5S rDNA), http://rose.man/poznan.pl/5SData/index.html. This edition of the database contains 1985primary structures of 5S rRNA and 5S rDNA.

Is the 5S RNA a primitive ribosomal sequence? [PDF]
Proceedings of the National Academy of Sciences, 1985 A tandemly arranged cluster of 55 RNA-like sequences in the middle of ribosomal 26S to 28S rRNAs from divergent eukaryotic organisms raises the possibility that the larger ribosomal RNAs were built up, at least in part, by gene amplification events and suggests an intriguing evolutionary relationship between the 55 rRNA and the larger rRNA molecules.
