Ribonucleoprotein complexes in neurologic diseases
Current Opinion in Neurobiology, 2008Ribonucleoprotein (RNP) complexes regulate the tissue-specific RNA processing and transport that increases the coding capacity of our genome and the ability to respond quickly and precisely to the diverse set of signals. This review focuses on three proteins that are part of RNP complexes in most cells of our body: TAR DNA-binding protein (TDP-43), the

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 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 cytoplasmic 10S ribonucleoprotein particle (iRNP), which is isolated from chick embryonic muscle, is a potent inhibitor of mRNA translation in vitro and contains a 4S translation inhibitory RNA species (iRNA). The iRNP particle shows similarity in size to the small nuclear ribonucleoprotein (snRNP) particles.

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 ...

Heterogeneous nuclear ribonucleoprotein complexes
Molecular Biology Reports, 1990Heterogeneous nuclear r ibonuc leopro te ins (hnRNPs) associate with RNA polymerase II transcripts immediately following the initiation of transcription to form hnRNP complexes. These structures are the functional assemblies within which hnRNAs and pre-mRNAs exist in the nucleus.

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.
