The small nuclear RNAs of Drosophila

Journal of Molecular Biology, 1984
We have investigated the sequences of the major small nuclear RNAs of Drosophila cultured cells, with the objective of elucidating phylogenetically conserved primary and secondary structures by comparison of the data with previously determined sequences of these RNAs in vertebrate species.

Small nuclear RNAs and translation

Journal of Cellular Physiology, 1983
AbstractThe possibility that small nuclear RNA species U1 might be involved in the inhibition of protein synthesis that occurs during mitosis has been explored. Upon exposure of mitotic HeLa cell extracts to 1% sodium deoxycholate, the majority of the rapidly sedimenting U1 RNA shifted to lower sedimentation rates.

Small Nuclear RNAs and RNA Processing

1983
I. Summary Ribosomal RNA, transfer RNA, and messenger RNAs, which comprise about 99% of the cellular RNA, are part of the protein-synthesizing machinery. Many studies in the last 15 years have established the presence of another class of RNA, “small nuclear RNAs” (snRNAs) that account for 0.1-1% of the total cellular RNA.

Small Nuclear RNA U2 Is Base-Paired to Heterogeneous Nuclear RNA

Science, 1982
Eukaryotic cells contain a set of low molecular weight nuclear RNA's. One of the more abundant of these is termed U2 RNA. The possibility that U2 RNA is hydrogen-bonded to complementary sequences in other nuclear RNA's was investigated. Cultured human (HeLa) cells were treated with a psoralen derivative that cross-links RNA chains that are base-paired ...

Subnuclear particles containing a small nuclear RNA and heterogeneous nuclear RNA

Journal of Molecular Biology, 1981
Abstract Five of the stable low molecular weight RNA species in the HeLa cell nucleus have been localized in RNP complexes in the cell nucleus. The two abundant species C and D and the three minor species F, G′ and H are found in RNP particles following two different methods of preparation.

The status of small nuclear RNA in the ribonucleoprotein fibrils containing heterogeneous nuclear RNA

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1981
hnRNP are made of two classes of unit, monoparticles and heterogeneous complexes. The monoparticles are much more easily dissociated by salt than the heterogeneous complexes. We made use of this differential salt sensitivity to determine the localization of snRNA in hnRNP.

Non-coding RNAs: lessons from the small nuclear and small nucleolar RNAs

Nature Reviews Molecular Cell Biology, 2007
Recent advances have fuelled rapid growth in our appreciation of the tremendous number, diversity and biological importance of non-coding (nc)RNAs. Because ncRNAs typically function as ribonucleoprotein (RNP) complexes and not as naked RNAs, understanding their biogenesis is crucial to comprehending their regulation and function.
