A large nucleolar U3 ribonucleoprotein required for 18S ribosomal RNA biogenesis

Nature, 2002
Although the U3 small nucleolar RNA (snoRNA), a member of the box C/D class of snoRNAs, was identified with the spliceosomal small nuclear RNAs (snRNAs) over 30 years ago, its function and its associated protein components have remained more elusive. The U3 snoRNA is ubiquitous in eukaryotes and is required for nucleolar processing of pre-18S ribosomal

Nucleotide sequence of Xenopus laevis 18S ribosomal RNA inferred from gene sequence

Nature, 1981
18S ribosomal RNA in Xenopus laevis is 1,825 nucleotides long, as inferred from sequence analysis of an 18S gene. All the 40 rRNA methyl groups can be located in the sequence. Comparison with the yeast (Saccharomyces cerevisiae) 18S sequence reveals extensive regions of high homology interspersed with tracts having little or no homology.

Nucleotide sequence of a mosquito 18S ribosomal RNA gene

Biochimica et Biophysica Acta (BBA) - Gene Structure and Expression, 1991
We have sequenced an 18S ribosomal RNA gene from the mosquito, Aedes albopictus. Computer alignment of the 1950 nucleotide coding region (56% A + T) with 18S rRNA sequences from two insect and three vertebrate species revealed greater sequence divergence among the insects than among the vertebrates.

Messenger RNA intron in the nuclear 18s ribosomal RNA gene of deuteromycetes

Current Genetics, 1993
Introns within messenger RNA genes have characteristic border sequences and a conserved region near the 3' end of the intron. All are involved in splicing to produce the mature mRNA. Introns in ribosomal RNA genes have less well-defined borders and contain no internal conservation.

Nuclear retention of 18S ribosomal RNA by human myeloma cells

Cell and Tissue Research, 1979
Normal quiescent lymphocytes regulate their ribosome content by selectively degrading newly synthesized 18S ribosomal RNA. Unlike actively dividing HeLa cells, lymphocytes retain 18S ribosomal RNA in the nucleus after synthesis instead of immediately transporting it to the cytoplasm.

Analysis of the 18S ribosomal RNA gene of Strongyloides stercoralis

International Journal for Parasitology, 1993
The entire 1766 bases of the 18S rRNA gene of Strongyloides stercoralis have been sequenced. The gene has a 38% G+C content. Although it is similar in length to the 18S rRNA gene of Caenorhabditis elegans, the only other completely sequenced nematode 18S rRNA gene, it is only 69% identical.

Cloning and Sequencing of a Human 18S Ribosomal RNA Gene

DNA, 1985
A clone containing an 18S ribosomal RNA (rRNA) gene has been isolated from a human genomic library constructed in lambda Charon 4A. This gene was sequenced and found to be 1868 bp long. The sequence divergencies in the human 18S rRNA gene and the previously sequenced mouse and rat genes are found in one G + C-rich region of 110 bp located in the 5 ...

Systematics of Holometabolous Insect Orders Based on 18S Ribosomal RNA

Molecular Phylogenetics and Evolution, 1993
Phylogenetic relationships of 19 species representing nine holometabolous insect orders and three outgroup orders were examined using sequence data from two-thirds of the 18S nuclear ribosomal RNA molecule. Of 1330 aligned nucleotide sites in 19 taxa, 460 were variable and used for phylogenetic analysis.
