Autoantibodies to Ribonucleoproteins
Clinics in Rheumatic Diseases, 1985Presently we recognize at least 12 different autoantibodies that involve ribonucleoproteins as antigens in patients with SLE and other rheumatic diseases. Such autoantibodies have a number of clinically useful diagnostic associations. Moreover, they have proved to be powerful tools for understanding the structure and function of a variety of cellular ...

CHARACTERIZATION OF BRAIN RIBONUCLEOPROTEIN PARTICLES
Journal of Neurochemistry, 1979Abstract— Brain RNP particles were characterized to determine whether they play a role in the regulation of brain protein synthesis. RNP particles were isolated from the postribosomal supernatant of cerebral hemispheres of young rabbits, employing conditions which minimize adventitious protein‐RNA interactions.

Changes in hepatic ribonucleoproteins in Kwashiorkor
The Indian Journal of Pediatrics, 1973Using the toluidine blue-ammonium molybdate staining method, different types of RNPs were demonstrated in the hepatocytes of patients with kwashiorkor. DCR-I and DCR-III were found to be reduced. Nucleolar chromatin and nucleolar parachromatin showed an apparent increase.

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.

The nucleolus: a site of ribonucleoprotein maturation
Current Opinion in Cell Biology, 2003The nucleolus is the site of ribosomal RNA synthesis, processing and ribosome maturation. Various small ribonucleoproteins also undergo maturation in the nucleolus, involving RNA modification and RNA-protein assembly. Such steps and other activities of small ribonucleoproteins also take place in Cajal (coiled) bodies.

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

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 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

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.
