Antibodies in Ribonucleoproteins

Nature, 1960
IN many hypotheses concerning the mechanism of the immune response the nucleic acids have been assigned a role in the production of antibodies, although no clear evidence for their participation is yet available. As regards protein synthesis in general, there is reason for believing that the ribonucleoproteins lie in the pathway of this synthetic ...

Autoantibodies to Ribonucleoproteins

Clinics in Rheumatic Diseases, 1985
Presently 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 ...

Changes in hepatic ribonucleoproteins in Kwashiorkor

The Indian Journal of Pediatrics, 1973
Using 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.

CHARACTERIZATION OF BRAIN RIBONUCLEOPROTEIN PARTICLES

Journal of Neurochemistry, 1979
Abstract— 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.

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.

The nucleolus: a site of ribonucleoprotein maturation

Current Opinion in Cell Biology, 2003
The 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.

Biogenesis of small nucleolar ribonucleoproteins

Current Opinion in Cell Biology, 2002
Eukaryotic cells contain a very complex population of small nucleolar RNAs. They function, as small nucleolar ribonucleoproteins, in pre-ribosomal RNA processing reactions, and also guide methylation and pseudouridylation of ribosomal RNA, spliceosomal small nuclear RNAs, and possibly other cellular RNAs.

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.
