Detection of antibodies to small nuclear ribonucleoproteins and small cytoplasmic ribonucleoproteins using unlabeled cell extracts [PDF]
AbstractRNA molecules immunoprecipitated with sera from patients who have rheumatic diseases can be readily detected in polyacrylamide gels by using ethidium bromide and silver stains. With these stains, we found that RNA patterns characteristic of a broad range of specific small nuclear ribonucleoproteins and small cytoplasmic ribonucleoproteins were ...

RNA-Seq of the nucleolus reveals abundant SNORD44-derived small RNAs. [PDF]
Small non-coding RNAs represent RNA species that are not translated to proteins, but which have diverse and broad functional activities in physiological and pathophysiological states. The knowledge of these small RNAs is rapidly expanding in part through

Independent deposition of heterogeneous nuclear ribonucleoproteins and small nuclear ribonucleoprotein particles at sites of transcription. [PDF]
The major nuclear ribonucleoproteins (RNPs) involved in pre-mRNA processing are classified in broad terms either as small nuclear RNPs (snRNPs), which are major participants in the splicing reaction, or heterogeneous nuclear RNPs (hnRNPs), which traditionally have been thought to function in general pre-mRNA packaging.

Reconstitution of the U1 small nuclear ribonucleoprotein particle. [PDF]
Although the U1 small nuclear ribonucleoprotein particle (snRNP) was the first mRNA-splicing cofactor to be identified, the manner in which it functions in splicing is not precisely understood. Among the information required to understand how U1 snRNP participates in splicing, it will be necessary to know its structure.

Nuclear organization of splicing small nuclear ribonucleoproteins in adenovirus-infected cells [PDF]
We have studied the effect of adenovirus infection on the nuclear organization of splicing small nuclear ribonucleoproteins (snRNPs) in HeLa cells. In uninfected HeLa cells, snRNPs are widespread throughout the nucleoplasm but also are concentrated in specific nuclear structures, including coiled bodies, interchromatin granules, and perichromatin ...

Insights into the
The 164 bp U1 small nuclear (sn) RNA is one of the most abundant noncoding (nc) RNA in human cells, estimated to be in the region of 106 copies/cell. Although best known for its role in pre‐messenger RNA (mRNA) splicing events, research over the past 20 years has revealed diverse functions of this ncRNA in mammalian cell types.

U1RNP/lncRNA/Transcription Cycle Axis Promotes Tumorigenesis of Hepatocellular Carcinoma
As a component of the spliceosome, U1 small nuclear ribonucleoproteins (U1RNPs) play critical roles in RNA splicing, and recent studies have shown that U1RNPs could recruit long non-coding RNAs (lncRNAs) to chromatin which are involved in cancer ...

Small Nuclear Ribonucleoprotein Remodeling During Catalytic Activation of the Spliceosome [PDF]
Major structural changes occur in the spliceosome during its activation just before catalyzing the splicing of pre–messenger RNAs (pre-mRNAs). Whereas changes in small nuclear RNA (snRNA) conformation are well documented, little is known about remodeling of small nuclear ribonucleoprotein (snRNP) structures during spliceosome ...

Small nuclear ribonucleoprotein complexes of Drosophila melanogaster. [PDF]
We report here on the isolation and characterization of small nuclear ribonucleoproteins (snRNPs) and corresponding small nuclear RNA (snRNA) species from nuclei of Drosophila melanogaster. Velocity sedimentation in sucrose gradients was used to partially fractionate the RNPs; analysis of fractions so obtained suggests that, in general, one snRNP ...
