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 ...

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

Essential Assembly Factor Rpf2 Forms Novel Interactions within the 5S RNP in Trypanosoma brucei

open access: yesmSphere, 2017
Ribosome biogenesis is a highly complex and conserved cellular process that is responsible for making ribosomes. During this process, there are several assembly steps that function as regulators to ensure proper ribosome formation.

Physical mapping of the 5S ribosomal RNA genes in Arabidopsis thaliana by multi-color fluorescence in situ hybridization with cosmid clones.

open access: yesThe Plant Journal, 1997
The 5S ribosomal RNA genes were mapped to mitotic chromosomes of Arabidopsis thaliana by fluorescence in situ hybridization (FISH). In the ecotype Landsberg erecta, hybridization signals appeared on three pairs of chromosomes, two of which were ...

FISH-aimed karyotype analysis in Aconitum subgen : aconitum reveals excessive rDNA sites in tetraploid taxa [PDF]

open access: yes, 2018
The location of 5S and 35S rDNA sequences in chromosomes of four Aconitum subsp. Aconitum species was analyzed after fluorescence in situ hybridization (FISH). Both in diploids (2n = 2x = 16; Aconitum variegatum, A. degenii) and tetraploids (2n = 4× = 32;

UPF201 archaeal specific family members reveal structural similarity to RNA-binding proteins but low likelihood for RNA-binding function. [PDF]

open access: yesPLoS ONE, 2008
We have determined X-ray crystal structures of four members of an archaeal specific family of proteins of unknown function (UPF0201; Pfam classification: DUF54) to advance our understanding of the genetic repertoire of archaea. Despite low pairwise amino

Origin and evolution of organisms as deduced from 5S ribosomal RNA sequences.

open access: yesMolecular biology and evolution, 1987
A phylogenetic tree of most of the major groups of organisms has been constructed from the 352 5S ribosomal RNA sequences now available. The tree suggests that there are several major groups of eubacteria that diverged during the early stages of their ...
