Ribonucleoprotein interaction with mammalian monosomes
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1968Abstract A subcellular fraction containing RNA and protein was prepared from rabbit reticulocytes. This fraction had a sedimentation behavior which was different from reticulocyte ribosomal subunits, and was capable of stimulating polypeptide synthesis in a mammalian cell-free system.

A Ribonucleoprotein from Amphibian Gastrulæ
Nature, 1958DISAGGREGATION of amphibian embryos by agents which chelate calcium is succeeded by re-aggregation if the cells are returned to a medium containing calcium1. It is customary to consider that the removal of calcium from the environment of the cells is responsible for the loss of adhesion displayed in disaggregation.

Ribonucleoprotein localization in mouse oocytes
Methods, 2011RNA molecules rarely function alone in cells. For most RNAs, their function requires formation of various ribonucleoprotein (RNP) complexes. For example, mRNP composition can determine mRNA localization, translational repression, level of translation or mRNA stability. RNPs are usually studied by biochemical methods. However, biochemical approaches are

Dissociation of macromolecular ribonucleoprotein of yeast
Archives of Biochemistry and Biophysics, 1957Abstract In 0.01 M KH 2 PO 4 K 2 HPO 4 (1:4) the omission of MgSO 4 causes the dissociation of the 80 S particles into two components which have sedimentation coefficients of 60 S and 40 S , respectively. Recombination of the 60 S and 40 S particles to form the 80 S particles takes place when 0.001 M MgSO 4 or 0.001 M CaCl 2 is ...

Isolation of messenger-like ribonucleoproteins
Biochemistry, 1975Subribosomal and polyribosomal messenger ribonucleoproteins (mRNPs) were isolated from Ehrlich ascites tumor cells by a method involving sedimentation of polyribosomal and subribosomal particles, dissociation with EDTA, and rate-zonal sedimentation.

Influenza virus messenger ribonucleoprotein
Virology, 1975Abstract Evidence is presented which indicates that influenza virus messenger RNA exists on polysomes, not as free RNA but in the form of a ribonucleoprotein (RNP). The data make it appear extremely unlikely that the presence of RNP on polysomes is an artifact of the extraction procedure.

The SMN complex, an assemblyosome of ribonucleoproteins
Current Opinion in Cell Biology, 2002Spinal muscular atrophy is a common, often lethal, neurodegenerative disease that results from low levels of, or loss-of-function mutations in, the SMN (survival of motor neurons) protein. SMN oligomerizes and forms a stable complex with five additional proteins: Gemins 2-6. SMN also interacts with several additional proteins referred to as "substrates"
