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 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

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.

Messenger Ribonucleoprotein Particles
1982Messenger 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 ...

The Phlebovirus Ribonucleoprotein: An Overview
In negative strand RNA viruses, ribonucleoproteins, not naked RNA, constitute the template used by the large protein endowed with polymerase activity for replicating and transcribing the viral genome. Here we give an overview of the structures and functions of the ribonucleoprotein from phleboviruses.Ferron, François, Lescar, Julien

Ribonucleoprotein of Clostridium perfringens (BP6K)
Archives of Biochemistry and Biophysics, 1953Abstract A procedure has been presented for the isolation and purification of the ribonucleoprotein from lyophilized Clostridium perfringens (BP6K) cells. Separation of the ribonucleoprotein from the desoxyribonucleoprotein was effected by extracting the lyophilized cells with 0.14 M NaCl. The amino acid composition of the purified nucleoprotein was
