5SRNAdb: an information resource for 5S ribosomal RNAs [PDF]

open access: yesNucleic 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

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

open access: yesScientific 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]

open access: yesComparative 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]

open access: yesComparative 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]

open access: yesPLoS 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]

open access: yesPLoS 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 ...

Heterochromatic siRNAs and DDM1 independently silence aberrant 5S rDNA transcripts in Arabidopsis. [PDF]

open access: yesPLoS 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 ...

Cytogenetic markers using single-sequence probes reveal chromosomal locations of tandemly repetitive genes in scleractinian coral Acropora pruinosa

open access: yesScientific 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.

Role of the RNA-binding protein ZC3H41 in the regulation of ribosomal protein messenger RNAs in trypanosomes

open access: yesParasites & 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 ...
