The biological function and clinical significance of SF3B1 mutations in cancer

open access: yesBiomarker Research, 2020
Spliceosome mutations have become the most interesting mutations detected in human cancer in recent years. The spliceosome, a large, dynamic multimegadalton small nuclear ribonucleoprotein composed of small nuclear RNAs associated with proteins, is ...

Defective minor spliceosome mRNA processing results in isolated familial growth hormone deficiency [PDF]

open access: yes, 2014
The molecular basis of a significant number of cases of isolated growth hormone deficiency remains unknown. We describe three sisters affected with severe isolated growth hormone deficiency and pituitary hypoplasia caused by biallelic mutations in the ...

The RNA Binding Protein Bcas2 is Required for Antibody Class Switch in Activated‐B Cells

open access: yesExploration, EarlyView.
Bcas2 recruits DHX15 and SRSF7 to form a protein complex for the splicing of CSR‐related mRNA at the 5' ss and 3' ss, generating two mature mRNA isoforms, which are ultimately translated into CSR‐related proteins. These CSR‐related proteins bind to DNA associated with antibodies, affecting the DSB repair of the relevant DNA after AID induction, thereby

A Quantitative Approach to Investigating the Hypothesis of Prokaryotic Intron Loss [PDF]

open access: yes, 2011
Using a novel method, we show that ordered triplets of motifs usually associated with spliceosomal intron recognition are underrepresented in the protein coding sequence of complete Thermotogae, archaeal and bacterial genomes.

Multi‐Cohort Analysis Reveals Genetic Predispositions to Clonal Hematopoiesis as Mutation‐Specific Risk Factors for Stroke

open access: yesAdvanced Genetics, Volume 6, Issue 1, March 2025.
This study comprehensively evaluated the differential effect of clonal hematopoiesis (CH) mutations on the risk of various stroke subtypes and functional recovery. It shows that TET2 is associated with small vessel stroke possibly via a pro‐inflammatory pathway. Abstract Recent observational studies have found an association between Clonal Hematopoesis

Nuclear Pre-snRNA Export Is an Essential Quality Assurance Mechanism for Functional Spliceosomes

open access: yesCell Reports, 2019
Summary: Removal of introns from pre-mRNAs is an essential step in eukaryotic gene expression, mediated by spliceosomes that contain snRNAs as key components. Although snRNAs are transcribed in the nucleus and function in the same compartment, all except

Immunoprecipitation of spliceosomal RNAs by antisera to galectin-1 and galectin-3 [PDF]

open access: yes, 2006
We have shown that galectin-1 and galectin-3 are functionally redundant splicing factors. Now we provide evidence that both galectins are directly associated with spliceosomes by analyzing RNAs and proteins of complexes immunoprecipitated by galectin ...

Origin and evolution of spliceosomal introns [PDF]

open access: yesBiology Direct, 2012
AbstractEvolution of exon-intron structure of eukaryotic genes has been a matter of long-standing, intensive debate. The introns-early concept, later rebranded ‘introns first’ held that protein-coding genes were interrupted by numerous introns even at the earliest stages of life's evolution and that introns played a major role in the origin of proteins

Evidence of Involvement of the Calcitonin Gene‐Related Peptide in Restless Legs Syndrome

open access: yesMovement Disorders, EarlyView.
Abstract Background Restless legs syndrome (RLS) is a common sensory‐motor disorder characterized by an urge to move the legs, often with unpleasant sensations, particularly during rest. Current treatments include iron supplementation, dopamine agonists, and opioids, but new therapeutic approaches are needed.

Minor introns are embedded molecular switches regulated by highly unstable U6atac snRNA

open access: yeseLife, 2013
Eukaryotes have two types of spliceosomes, comprised of either major (U1, U2, U4, U5, U6) or minor (U11, U12, U4atac, U6atac; <1%) snRNPs. The high conservation of minor introns, typically one amidst many major introns in several hundred genes ...
