Changes in intranuclear mobility of mature snRNPs provide a mechanism for splicing defects in spinal muscular atrophy [PDF]

, 2012
This work was funded by the Wellcome Trust (grant ID WT078810MA)It is becoming increasingly clear that defects in RNA metabolism can lead to disease. Spinal muscular atrophy (SMA), a leading genetic cause of infant mortality, results from insufficient ...

Capturing Hu Antigen R Domain Closure Through Supervised Molecular Dynamics Simulations

ChemMedChem, Volume 21, Issue 19, 14 October 2026.
HuR is a therapeutically relevant RNA‐binding protein that switches from an open apo form to a closed RNA‐bound one. Its atomistic detail is unknown. Here, Supervised Molecular Dynamics is applied for the first time to an intramolecular event: a multistep supervision of interdomain distances reproduces a plausible closure pathway and reveals transient ...

Arginine methylation as a regulatory ratchet in cancer: From substrate selection to malignant‐state stabilization

Molecular Oncology, Volume 20, Issue 10, Page 2466-2489, October 2026.
Arginine methylation can be viewed as a persistence‐prone post‐translational modification regulated by a network of PRMTs. Competitive and compensatory interactions among PRMTs can redistribute methylation across substrate pools shaped by sequence, structural, spatial, and environmental layers, reinforcing RNA‐processing, chromatin, and signaling ...

Cloning and intracellular localization of the U2 small nuclear ribonucleoprotein auxiliary factor small subunit

, 1992
U2 small nuclear ribonucleoprotein auxiliary factor (U2AF), an essential mammalian splicing factor, is composed of two subunits: a 65-kDa protein (U2AF65), which binds the pre-mRNA polypyrimidine tract and is required for in vitro splicing, and an ...

Isoforms of U1-70k control subunit dynamics in the human spliceosomal U1 snRNP [PDF]

, 2009
Most human protein-encoding genes contain multiple exons that are spliced together, frequently in alternative arrangements, by the spliceosome. It is established that U1 snRNP is an essential component of the spliceosome, in human consisting of RNA and ...

RNA‐Binding Proteins: Function, Biological Mechanisms, and Therapeutic Opportunities

MedComm, Volume 7, Issue 9, September 2026.
RNA‐binding proteins (RBPs) regulate RNA stability, localization, translation, and splicing through intrinsic binding domains and interactions with diverse cellular partners. Their competitive and cooperative networks shape disease‐related RNA programs, especially in cancer.

RNA polymerase I transcription and pre-rRNA processing are linked by specific SSU processome components [PDF]

, 2004
Sequential events in macromolecular biosynthesis are often elegantly coordinated. The small ribosomal subunit (SSU) processome is a large ribonucleoprotein (RNP) required for processing of precursors to the small subunit RNA, the 18S, of the ribosome. We

DHX15 affects AML1‐ETO9a splicing together with HNRNPL, RBM33 in AML1‐ETO‐positive acute myeloid leukaemia

British Journal of Haematology, Volume 209, Issue 3, Page 964-977, September 2026.
Moderate DHX15, HNRNPL and RBM33 expression drives predominant AML1‐ETO mRNA production, while elevated expression of them promotes generating more AE9a mRNA (Aspartic acid ‐ Glutamic acid ‐ Alanine ‐ Aspartic acid sequence)(messenger ribonucleic acid).

Targeting m6A Modifications Regulating Ferroptosis Offers Novel Therapy in Diseases

Cell Proliferation, Volume 59, Issue 9, September 2026.
m6A RNA modification regulates ferroptosis by balancing iron metabolism, lipid peroxidation, and antioxidant defenses. Dysregulated m6A signaling disrupts pro‐ and anti‐ferroptotic factors, leading to excess ROS, Fe3+ accumulation, and lipid peroxidation–driven cell death. Targeting m6A‐mediated ferroptotic regulation represents a promising therapeutic
