A sart1 Zebrafish Mutant Results in Developmental Defects in the Central Nervous System

Cells, 2020
The spliceosome consists of accessory proteins and small nuclear ribonucleoproteins (snRNPs) that remove introns from RNA. As splicing defects are associated with degenerative conditions, a better understanding of spliceosome formation and function is ...

Evidence for a nuclear compartment of transcription and splicing located at chromosome domain boundaries [PDF]

, 1993
The nuclear topography of splicing snRNPs, mRNA transcripts and chromosome domains in various mammalian cell types are described. The visualization of splicing snRNPs, defined by the Sm antigen, and coiled bodies, revealed distinctly different ...

The C-group Heterogeneous Nuclear Ribonucleoprotein Proteins Bind to the 5′ Stem-Loop of the U2 Small Nuclear Ribonucleoprotein Particle [PDF]

Journal of Biological Chemistry, 1996
The C-group heterogeneous nuclear ribonucleoprotein (hnRNP) proteins bind to nascent pre-messenger RNA. In vitro studies have indicated that the C hnRNP proteins bind particularly strongly to the intron polypyrimidine tract of pre-mRNA and may be important for pre-mRNA splicing.

Spontaneous Non‐Catalyzed Molecular Reactions and Interactions in the Human Body: Biomedical Implications

Advanced Science, EarlyView.
ABSTRACT The human body functions as a natural reactor for a vast network of chemical and biological reactions and physical interactions among small molecules, proteins, cells, and numerous other components. These reactions/interactions are essential for maintaining normal physiological functions.

SNUPN deficiency causes a recessive muscular dystrophy due to RNA mis-splicing and ECM dysregulation

Nature Communications
SNURPORTIN-1, encoded by SNUPN, plays a central role in the nuclear import of spliceosomal small nuclear ribonucleoproteins. However, its physiological function remains unexplored.

U1 small nuclear ribonucleoprotein studied by in vitro assembly. [PDF]

The Journal of cell biology, 1983
The small nuclear RNAs are known to be complexed with proteins in the cell (snRNP). To learn more about these proteins, we developed an in vitro system for studying their interactions with individual small nuclear RNA species. Translation of HeLa cell poly(A)+ mRNA in an exogenous message-dependent reticulocyte lysate results in the synthesis of snRNP ...

A Drosophila Model of Spinal Muscular Atrophy Uncouples snRNP Biogenesis Functions of Survival Motor Neuron from Locomotion and Viability Defects

Cell Reports, 2012
The spinal muscular atrophy (SMA) protein, survival motor neuron (SMN), functions in the biogenesis of small nuclear ribonucleoproteins (snRNPs). SMN has also been implicated in tissue-specific functions; however, it remains unclear which of these is ...
