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 ...

rRNA loss induced by rifampicin addition in Escherichia coli reflects extraction artifacts rather than in vivo degradation [PDF]

Scientific Reports
When measuring RNA stability in Escherichia coli, RNA synthesis is usually stopped using rifampicin. Although rRNAs are considered stable in vivo, Hamouche et al. Ribosomal RNA degradation induced by the bacterial RNA polymerase inhibitor rifampicin. RNA

Karyotype description and comparative chromosomal mapping of rDNA and U2 snDNA sequences in Eigenmannia limbata and E. microstoma (Teleostei, Gymnotiformes, Sternopygidae) [PDF]

Comparative Cytogenetics, 2022
The genus Eigenmannia Jordan et Evermann,1896 includes electric fishes endemic to the Neotropical region with extensive karyotype variability and occurrence of different sex chromosome systems, however, cytogenetic studies within this group are ...

Karyotypic analysis and isolation of four DNA markers of the scleractinian coral Favites pentagona (Esper, 1795) (Scleractinia, Anthozoa, Cnidaria) [PDF]

Comparative Cytogenetics, 2022
We performed conventional and molecular cytogenetic studies on the Favites pentagona Esper, 1795, a scleractinian coral mostly found along the west coast of Japan. Karyotype analysis of F.

A novel association between two trypanosome-specific factors and the conserved L5-5S rRNA complex. [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 involved in and essential for ribosome biogenesis.

Non-canonical binding interactions of the RNA recognition motif (RRM) domains of P34 protein modulate binding within the 5S ribonucleoprotein particle (5S RNP). [PDF]

PLoS ONE, 2017
RNA binding proteins are involved in many aspects of RNA metabolism. In Trypanosoma brucei, our laboratory has identified two trypanosome-specific RNA binding proteins P34 and P37 that are involved in the maturation of the 60S subunit during ribosome ...

5S Ribosomal RNA Database [PDF]

Nucleic 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).

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 ...

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.
