D-RNA Containing Ribonucleoprotein Particles

1971
This paper will deal with ribonucleoprotein particles containing D-RNA or RNA with a DNAlike base composition. This RNA is characterized by a high AU-content, heterogeneity with respect to molecular weight, a relatively rapid turnover, and the ability to stimulate amino acid incorporation in a cell-free system.

Antigenic relatedness of small ribonucleoprotein particles

Biochimica et Biophysica Acta (BBA) - General Subjects, 1984
We have examined the relationships among small ribonucleoprotein particles found in eucaryotic cells by an antigen depletion technique using autoimmune antibodies. We have confirmed that the (U1) ribonucleoprotein particle antigen is found on the same complex as the Sm antigen.

Axonal transport of ribonucleoprotein particles (Vaults)

Neuroscience, 1999
RNA was previously shown to be transported into both dendritic and axonal compartments of nerve cells, presumably involving a ribonucleoprotein particle. In order to reveal potential mechanisms of transport we investigated the axonal transport of the major vault protein of the electric ray Torpedo marmorata.

Messenger ribonucleoprotein particles in silkmoth oogenesis

Developmental Biology, 1976
Silkmoth oocytes contain significant amounts of nontranslating cytoplasmic messenger RNA apparently stored until fertilization. The physical state of this mRNA was examined by bouyant density centrifugation on cesium chloride gradients. Messenger elements were isolated either by oligo(dT) cellulose chromatography or by separation of ooplasm on sucrose ...

cDNA library generation from ribonucleoprotein particles

Nature Protocols, 2011
Most, if not all, known noncoding RNAs (ncRNAs) are associated with RNA binding proteins, thus forming ribonucleoprotein particles or RNPs. Here we describe a protocol for the generation of a specialized cDNA library from RNPs, thereby increasing the proportion of functional ncRNA species in the library.

Informational ribonucleoprotein particles of newt oocytes: Polyribosome-associated ribonucleoproteins

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1974
Various species of rapidly labelled, informational ribonucleoproteins can be isolated from homogenates of newt oocytes. Polyribosome-associated ribonucleoprotein can be separated from heterogeneous nuclear ribonucleoprotein and free cytoplasmic ribonucleoprotein by sucrose gradient centrifugation.

Nuclear ribonucleoprotein particles associated with DNA

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1969
Abstract 1. 1. Nuclear ribonucleoprotein particles, prepared from isolated calf thymus nuclei, under the conditions adopted in these experiments, contained 4.0±0.26% DNA. 2. 2. Sucrose density gradient electrophoresis analyses of the DNA present in the ribonucleoprotein preparations showed that DNA was present largely on ribonucleoprotein ...

Messenger Ribonucleoprotein Particles

1982
Messenger RNA, from the time of its synthesis in the nucleus through its translation and degradation, does not exist as free RNA in animal cells but rather always appear to be complexed with proteins. Free cytoplasmic ribonucleoprotein (RNP) particles containing non-ribosomal RNA were discovered by Spirin and coworkers (1) in 1964 and were called ...

Ribonucleoprotein particles of quiescent maize embryonic axes

Plant Molecular Biology, 1998
Certain RNA molecules are known to be sequestered and stored as ribonucleoprotein particles (RNPs) in many different tissues, particularly at some stages of metabolic quiescence. In this research RNPs from embryonic axes of mature maize seeds were isolated by sucrose and CsCl gradient centrifugation and characterized based on their RNA and protein ...
