5S Ribosomal RNA Database [PDF]

open access: yesNucleic Acids Research, 2002
Ribosomal 5S RNA (5S rRNA) is an integral component of the large ribosomal subunit in all known organisms with the exception only of mitochondrial ribosomes of fungi and animals. It is thought to enhance protein synthesis by stabilization of a ribosome structure. This paper presents the updated database of 5S rRNA and their genes (5S rDNA).

Identification of planorbids from Venezuela by polymerase chain reaction amplification and restriction fragment length polymorphism of internal transcriber spacer of the RNA ribosomal gene.

open access: yesMemórias do Instituto Oswaldo Cruz, 2000
Snails of the genus Biomphalaria from Venezuela were subjected to morphological assessment as well as polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) analysis.

Ribosomal history reveals origins of modern protein synthesis. [PDF]

open access: yesPLoS 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.

Genomic function during the lampbrush chromosome stage of amphibian oogenesis [PDF]

open access: yes, 1966
Throughout its lengthy developmental history the disposition of the genetic material in the amphibian oocyte nucleus differs from that in other cell types.

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

open access: yesBMC 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 ...

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

open access: yesCell 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).

Orchestrating ribosomal RNA folding during ribosome assembly

open access: yesBioEssays, 2022
AbstractConstruction of the eukaryotic ribosome is a complex process in which a nascent ribosomal RNA (rRNA) emerging from RNA Polymerase I hierarchically folds into a native three‐dimensional structure. Modular assembly of individual RNA domains through interactions with ribosomal proteins and a myriad of assembly factors permit efficient ...

Idiosyncratic evolution of conserved eukaryote proteins that are similar in sequence to archaeal or bacterial proteins [PDF]

open access: yes, 2008
Sequence comparisons have been made between the proteins of 571 prokaryote species including 46 archaea and 525 bacteria and the set of human proteins.

RNA polymerase I mutant affects ribosomal RNA processing and ribosomal DNA stability

open access: yesRNA 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.

Ribosomal RNA regulates chromosome clustering during mitosis

open access: yesCell 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.
