A genome-wide function of THSC/TREX-2 at active genes prevents transcription–replication collisions
(Oxford University Press, 2014)
The THSC/TREX-2 complex of Saccharomyces cerevisiae mediates the anchoring of transcribed genes to the nuclear pore, linking transcription elongation with mRNA export and genome stability, as shown for specific reporters. ...

An hpr1 point mutation that impairs transcription and mRNP biogenesis without increasing recombination
(American Society for Microbiology, 2006)
THO/TREX, a conserved eukaryotic protein complex, is a key player at the interface between transcription and mRNP metabolism. The lack of a functional THO complex impairs transcription, leads to transcriptiondependent ...

DDX47, MeCP2, and other functionally heterogeneous factors protect cells from harmful R loops
(Elsevier, 2023)
Unscheduled R loops can be a source of genome instability, a hallmark of cancer cells. Although targeted proteomic approaches and cellular analysis of specific mutants have uncovered factors potentially involved in R-loop ...

Tho1, a novel hnRNP, and Sub2 provide alternative pathways for mRNP biogenesis in yeast THO mutants
(American Society for Microbiology, 2006)
THO is a protein complex that functions in cotranscriptional mRNP formation. Yeast THO1 and SUB2 (Saccharomyces cerevisiae) were identified as multicopy suppressors of the expression defects of the hpr1 mutant of THO. ...

Excess of Yra1 RNA-Binding Factor Causes Transcription-Dependent Genome Instability, Replication Impairment and Telomere Shortening
(Public Library of Science, 2016)
Yra1 is an essential nuclear factor of the evolutionarily conserved family of hnRNP-like export factors that when overexpressed impairs mRNA export and cell growth. To investigate further the relevance of proper Yra1 ...
