Surprisingly high number of Twintrons in vertebrates

open access: yesBiology Direct, 2013
Twintrons represent a special intronic arrangement in which introns of two different types occupy the same gene position. Consequently, alternative splicing of these introns requires two different spliceosomes competing for the same RNA molecule. So far,

The phosphorylation of Prp1p by Prp4p-kinase is required for the activation of pre-catalytic spliceosomes [PDF]

open access: yes, 2006
Die Rolle von Prp1p und seiner Phosphorylierung durch die Prp4p-Kinase beim Aufbau und der Aktivierung von Spleißosomen wurde untersucht. Prp1p und Prp31p werden unabhängig von der Prp4p-Kinaseaktivität an prä-katalytische Komplexe gebunden, die entweder

U12 type introns were lost at multiple occasions during evolution

open access: yesBMC Genomics, 2010
Background Two categories of introns are known, a common U2 type and a rare U12 type. These two types of introns are removed by distinct spliceosomes. The phylogenetic distribution of spliceosomal RNAs that are characteristic of the U12 spliceosome, i.e.

Aspartyl-tRNA synthetase 2 orchestrates iron-sulfur metabolism in hematopoietic stem cells via fine-tuning alternative RNA splicing

open access: yesCell Reports, 2023
Summary: Aspartyl-tRNA synthetase 2 (Dars2) is involved in the regulation of mitochondrial protein synthesis and tissue-specific mitochondrial unfolded protein response (UPRmt).

A day in the life of the spliceosome [PDF]

open access: yesNature Reviews Molecular Cell Biology, 2014
One of the most amazing findings in molecular biology was the discovery that eukaryotic genes are discontinuous, interrupted by stretches of non-coding sequence. The subsequent realization that the intervening regions are removed from pre-mRNA transcripts via the activity of a common set of small nuclear RNAs (snRNAs), which assemble together with ...

Intron lariat spliceosomes convert lariats to true circles: implications for intron transposition. [PDF]

open access: yesGenes Dev
Rare, full-length circular intron RNAs distinct from lariats have been reported in several species, but their biogenesis is not understood. We envisioned and tested a hypothesis for their formation using Saccharomyces cerevisiae, documenting full-length ...

Defective minor spliceosomes induce SMA-associated phenotypes through sensitive intron-containing neural genes in Drosophila

open access: yesNature Communications, 2020
Spinal muscular atrophy (SMA) is associated with minor splicing-related defects. Here the authors develop Drosophila models with minor spliceosomal-snRNA deletions, and demonstrate SMA-like phenotypes.

Effects of GYP mRNA alternative splicing on cell surface localization of MNS blood group glycoprotein GPA and GPB

open access: yesZhongguo shuxue zazhi, 2022
Objective To analyze the polymorphisms of GYPA and GYPB mRNA spliceosomes associated with MNS blood group, and to explore the mechanism of subcellular localization of GPA and GPB protein isomerism encoded by various spliceosomes as well as the expression

PANoptosis in the pathogenesis of myelodysplastic syndromes

open access: yesMolecular Oncology, EarlyView.
PANoptosis, a combination of three types of programmed cell death, is mediated by a large protein complex called a PANoptosome. In healthy bone marrow hematopoietic cells, PANoptosis is restricted by inhibitory signaling. In MDS, bone marrow cells become sensitive to the PANoptotic stimuli due to the aberrant inactivation of inhibitory signaling or ...
