Excised linear introns regulate growth in yeast

JT Morgan, GR Fink, DP Bartel - Nature, 2019 - nature.com

[HTML][HTML] Profiling lariat intermediates reveals genetic determinants of early and late co-transcriptional splicing

Y Zeng, BJ Fair, H Zeng, A Krishnamohan, Y Hou… - Molecular cell, 2022 - cell.com
Long introns with short exons in vertebrate genes are thought to require spliceosome
assembly across exons (exon definition), rather than introns, thereby requiring transcription …

SF3b1 mutations associated with myelodysplastic syndromes alter the fidelity of branchsite selection in yeast

TJ Carrocci, DM Zoerner, JC Paulson… - Nucleic acids …, 2017 - academic.oup.com
RNA and protein components of the spliceosome work together to identify the 5΄ splice site,
the 3΄ splice site, and the branchsite (BS) of nascent pre-mRNA. SF3b1 plays a key role in …

THUMPD2 catalyzes the N2-methylation of U6 snRNA of the spliceosome catalytic center and regulates pre-mRNA splicing and retinal degeneration

WQ Yang, JY Ge, X Zhang, WY Zhu, L Lin… - Nucleic Acids …, 2024 - academic.oup.com
The mechanisms by which the relatively conserved spliceosome manages the enormously
large number of splicing events that occur in humans (∼ 200 000 versus∼ 300 in yeast) are …

[HTML][HTML] RNA-dependent chromatin association of transcription elongation factors and Pol II CTD kinases

S Battaglia, M Lidschreiber, C Baejen, P Torkler… - Elife, 2017 - elifesciences.org
