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/)

PWP1 promotes nutrient-responsive expression of 5S ribosomal RNA [PDF]
Biology Open, 2018 PWP1 is a chromatin binding protein with an important role in animal growth control downstream of mTOR-mediated nutrient sensing. PWP1 has been shown to control tissue growth by promoting the transcription of 5.8S, 18S and 28S ribosomal RNAs (rRNAs) by ...

Mirror-Image 5S Ribonucleoprotein Complexes [PDF]
, 2020 After realizing mirror-image genetic replication, transcription, and reverse transcription, the biggest challenge in establishing a mirror-image version of the central dogma is to build a mirror-image ribosome-based translation machine.

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.

Mediating Ribosomal Competition by Splitting Pools [PDF]
LCSS Vol 5 Issue 5 (Nov 2020), 2020 Synthetic biology constructs often rely upon the introduction of "circuit" genes into host cells, in order to express novel proteins and thus endow the host with a desired behavior. The expression of these new genes "consumes" existing resources in the cell, such as ATP, RNA polymerase, amino acids, and ribosomes. Ribosomal competition among strands of

Scientific Reports, 2021 The short and similar sized chromosomes of Acropora pose a challenge for karyotyping. Conventional methods, such as staining of heterochromatic regions, provide unclear banding patterns that hamper identification of such chromosomes.

Parasites & Vectors, 2023 Background Trypanosomes are single-celled eukaryotes that rely heavily on post-transcriptional mechanisms to regulate gene expression. RNA-binding proteins play essential roles in regulating the fate, abundance and translation of messenger RNAs (mRNAs ...

Polysomally Protected Viruses [PDF]
Phys. Biol. 18 046009 (2021), 2021 It is conceivable that an RNA virus could use a polysome, that is, a string of ribosomes covering the RNA strand, to protect the genetic material from degradation inside a host cell. This paper discusses how such a virus might operate, and how its presence might be detected by ribosome profiling.

The long-range interaction map of ribosomal DNA arrays. [PDF]
PLoS Genetics, 2018 The repeated rDNA array gives rise to the nucleolus, an organelle that is central to cellular processes as varied as stress response, cell cycle regulation, RNA modification, cell metabolism, and genome stability.

Growth-laws and invariants from ribosome biogenesis in lower Eukarya [PDF]
Phys. Rev. Research 3, 013020 (2021), 2020 Eukarya and Bacteria are the most evolutionarily distant domains of life, which is reflected by differences in their cellular structure and physiology. For example, Eukarya feature membrane-bound organelles such as nuclei and mitochondria, whereas Bacteria have none.
