Compilation of 5S rRNA and 5S rRNA gene sequences
This is an update for the 5S rRNA sequences of the BERLIN RNA DATABANK last published in 1990 (1). The new entry consists of 25 eubacterial and 2 eukaryotic 5S rRNA sequences and 10 plant 5S rRNA pseudogenes (Table 1). Thus the BERLIN RNA DATABANK contains as of February 1, 1991 the 5S rRNA sequences of 44 archaebacteria, 292 eubacteria, 20 plastids, 6 mitochondria, 321 eukaryotes and 21 eukary...
متن کامل5S rRNA Data Bank
In this paper we present the updated version of the compilation of 5S rRNA and 5S rDNA nucleotide sequences. It contains 1622 primary structures of 5S rRNAs and 5S rRNA genes from 888 species. These include 58 archaeal, 427 eubacterial, 34 plastid, nine mitochondrial and 1094 eukaryotic DNA or RNA nucleotide sequences. The sequence entries are divided according to the taxonomic position of the ...
متن کاملThe pre-existing population of 5S rRNA effects p53 stabilization during ribosome biogenesis inhibition
Pre-ribosomal complex RPL5/RPL11/5S rRNA (5S RNP) is considered the central MDM2 inhibitory complex that control p53 stabilization during ribosome biogenesis inhibition. Despite its role is well defined, the dynamic of 5S RNP assembly still requires further characterization. In the present work, we report that MDM2 inhibition is dependent by a pre-existing population of 5S rRNA.
متن کاملSymportin 1 chaperones 5S RNP assembly during ribosome biogenesis by occupying an essential rRNA-binding site
During 60S biogenesis, mature 5S RNP consisting of 5S RNA, RpL5 and RpL11, assembles into a pre-60S particle, where docking relies on RpL11 interacting with helix 84 (H84) of the 25S RNA. How 5S RNP is assembled for recruitment into the pre-60S is not known. Here we report the crystal structure of a ternary symportin Syo1-RpL5-N-RpL11 complex and provide biochemical and structural insights into...
متن کاملNucleotide sequence of cytoplasmic 5S rRNA from a eukaryotic thermophilic unicellular alga, Cyanidium caldarium.
From a total RNA extract of Cyanidium caldarium (Cca) cells we isolated, by the use of polyacrylamide gel electrophoresis under denaturing conditions, cytoplasmic 5S rRNA and determined its primary and possible secondary structure (Figure 1). The Cca 5S rRNA (i) is 124 nt long, (ii) harbors, at the expected positions, both internal transcription signals characteristic of this class of RNA polym...
