Dynamics and consequences of spliceosome E complex formation

open access: yeseLife, 2017
The spliceosome must identify the correct splice sites (SS) and branchsite (BS) used during splicing. E complex is the earliest spliceosome precursor in which the 5' SS and BS are defined.

RNA‐Binding Protein RBM25 Targets the mRNA Stability of GTPase Rab22a to Restrict Viral Entry and Infection

open access: yesAdvanced Science, EarlyView.
This study identifies RNA‐binding protein RBM25 as a broad‐spectrum antiviral factor acting independently of type I interferon. It blocks viral entry by suppressing GTPase Rab22a via the RC3H1‐mediated destabilization of Rab22a mRNA. Viral downregulation of RBM25 enhances GTPase Rab22a expression and viral entry, revealing an unreported post ...

RNA splicing: Unexpected spliceosome diversity

open access: yes, 1996
A novel form of spliceosome, containing the minor snRNPs U11 and U12, splices a class of pre-mRNA introns with non-consensus splice sites. This unexpected spliceosome diversity has interesting implications for the evolution and expression of eukaryotic ...

Transcriptome analysis of spliceosome inhibition in human cells

open access: yes, 2020
Recently, small molecule inhibitors of the spliceosome have been shown to have anti-tumour effects, yet their mechanism of cancer inhibition remains unknown.

Cooperative Analysis of Structural Dynamics in RNA-Protein Complexes by Single-Molecule Förster Resonance Energy Transfer Spectroscopy

open access: yesMolecules, 2020
RNA-protein complexes (RNPs) are essential components in a variety of cellular processes, and oftentimes exhibit complex structures and show mechanisms that are highly dynamic in conformation and structure.

De Novo 2.2 Mb 19q13.42–q13.43 Microdeletion Encompassing U2AF2: Support for a Haploinsufficiency Model

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT U2 small nuclear RNA auxiliary factor 2 (U2AF2) is an essential pre‐mRNA splicing factor involved in the early stages of pre‐mRNA splicing. To date, multiple individuals have been reported with predominantly heterozygous missense variants presenting intellectual disability, speech and motor delays, seizures, hypotonia, and thin or hypoplastic ...

The Spliceosome and Its Metal Ions

open access: yes, 2011
The spliceosome is a massive complex of 5 RNAs and many proteins that associate to catalyze precursor messenger RNA splicing. The process of splicing involves two phosphoryl transfer reactions that result in intron excision and ligation of the flanking ...

Microinflammation-Driven Gene Expression Dynamics in the Pathogenesis of Metabolic Disorders and Cancer

open access: yesBiology
Microinflammation serves as a central mechanism linking metabolic diseases and cancer. This study integrates gene expression profiles from irritable bowel syndrome (IBS), obesity, type 2 diabetes (T2D), colorectal cancer (CRC), renal cell carcinoma (RCC),

Prenatal Evaluation of RNU4‐2 Variants in Fetuses With Central Nervous System Anomalies

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Fetal central nervous system (CNS) anomalies are among the most common congenital malformations, yet the overall prenatal diagnostic yield of current genetic testing remains below 40%. Variants in RNU4‐2, a non‐coding gene encoding the U4 small nuclear RNA (snRNA), have recently been linked to a novel highly recurrent dominant ...
