Fine‐Tuned Regulation of mRNA Translation and Transport by STAU2 Condensate Facilitates Neuronal Development and Plasticity

Advanced Science, EarlyView.
STAU2 undergoes phase separation to form dynamic condensates that package target mRNAs and deliver them to the distal ends of growing neuronal dendrites. STAU2 condensates stabilize embedded mRNAs and repress their translation. Synaptic activity bidirectionally remodels STAU2 condensates, coordinating local translation of STAU2‐associated mRNAs ...

Diabetic polyneuropathy, sensory neurons, nuclear structure and spliceosome alterations: a role for CWC22

Disease Models & Mechanisms, 2017
Unique deficits in the function of adult sensory neurons as part of their early neurodegeneration might account for progressive polyneuropathy during chronic diabetes mellitus.

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.

ABHD17C‐Mediated S‐Depalmitoylation of BCL6B Enhances CD24 Transcription to Resist Macrophage Phagocytosis in Pancreatic Cancer

Advanced Science, EarlyView.
ABHD17C‐mediated depalmitoylation of BCL6B at Cys442 blocks its nuclear import and triggers ubiquitin‐dependent degradation, attenuating transcriptional repression of the anti‐phagocytic signal CD24. This mechanism enables pancreatic cancer cells to evade macrophage phagocytosis and fosters an immunosuppressive microenvironment.

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 ...

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 ...

SSR4 sustains Tertiary Lymphoid Structures by Regulation Quality Control of N‐linked Glycosylation During B‐cell Differentiation Into Plasmacyte in Colorectal Cancer

Advanced Science, EarlyView.
SSR4, a TRAP component induced in B cells, governs BAFFR N‐glycosylation via DDOST to sustain NF‐κB signaling, B‐cell differentiation, and TLS maturation. Its loss impairs anti‐tumor immunity, while overexpression improves antibody glycosylation and ADCC, revealing a critical regulator for cancer immunotherapy.

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.

Molecular Mobility of N‐Acetylgalactosamine‐Modified Cyclodextrins on a Polyrotaxane for Highly Efficient Liver Targeting of Antibody Chimeras and Genome‐Editing Ribonucleoproteins

Advanced Science, EarlyView.
Monovalent N‐acetylgalactosamine (GalNAc)‐modified polyrotaxane enables efficient liver targeting by utilizing ligand mobility. The sliding and rotating cyclic components i.e., cyclodextrin in the polyrotaxane dynamically cluster GalNAc moieties, thereby mimicking trivalent interactions with asialoglycoprotein receptors.
