Novel endoribonucleases as central players in various pathways of eukaryotic RNA metabolism [PDF]

open access: yes, 2010
For a long time it has been assumed that the decay of RNA in eukaryotes is mainly carried out by exoribonucleases, which is in contrast to bacteria, where endoribonucleases are well documented to initiate RNA degradation.

Organization and expression analysis of 5S and 45S ribosomal DNA clusters in autotetraploid Carassius auratus

open access: yesBMC Ecology and Evolution, 2021
Background Autotetraploid Carassius auratus (4n = 200, RRRR) (abbreviated as 4nRR) is derived from whole genome duplication of Carassius auratus red var. (2n = 100, RR) (abbreviated as RCC).

Distinct ribosome maturation defects in yeast models of Diamond-Blackfan anemia and Shwachman-Diamond syndrome

open access: yesHaematologica, 2010
Background Diamond-Blackfan anemia and Shwachman-Diamond syndrome are inherited bone marrow failure syndromes linked to defects in ribosome synthesis.

Purification of 70S Ribosomes from Bacillus subtilis

open access: yesBio-Protocol, 2015
The eubacterial ribosome (70S) is a macromolecular complex that is composed of a small (30S) subunit and a large (50S) subunit. The small subunit comprises the 16S ribosomal RNA (rRNA) and more than 20 ribosomal proteins (r-proteins), whereas the large ...

Molecular genetic analysis of siRNA biogenesis and function in Arabidopsis thaliana [PDF]

open access: yes, 2009
In diverse eukaryotes, small RNA products of Dicer-like (DCL) proteins regulate mRNA stability or translation, and direct chromatin modifications to genomic regions, phenomena collectively known as RNA silencing.

The complete chloroplast genome of Juniperus squamata (Cupressaceae), a shrubby conifer from Asian Mountains

open access: yesMitochondrial DNA. Part B. Resources, 2019
The complete chloroplast genome of Juniperus squamata, a shrubby conifer of ornamental value, is determined in this study. The complete chloroplast genome size is 127,792 bp in length.

In vitro Assessment of RNA Polymerase I Activity

open access: yesBio-Protocol, 2017
In eukaryotic cells transcriptional processes are carried out by three different RNA polymerases: RNA polymerase I which specifically transcribes ribosomal RNA (rRNA), RNA polymerase II which transcribes protein-coding genes to yield messenger RNAs ...

5S Ribosomal RNA Is an Essential Component of a Nascent Ribosomal Precursor Complex that Regulates the Hdm2-p53 Checkpoint

open access: yesCell Reports, 2013
Recently, we demonstrated that RPL5 and RPL11 act in a mutually dependent manner to inhibit Hdm2 and stabilize p53 following impaired ribosome biogenesis.

Kinetoplastid Specific RNA-Protein Interactions in Trypanosoma cruzi Ribosome Biogenesis. [PDF]

open access: yesPLoS ONE, 2015
RNA binding proteins (RBP) play essential roles in the highly conserved and coordinated process of ribosome biogenesis. Our laboratory has previously characterized two essential and abundant RBPs, P34 and P37, in Trypanosoma brucei which are required for
