Title: Structural insights into the nucleic acid remodeling mechanisms of the yeast THO-Sub2 complex.
Both THO and Yra1-C stimulated Sub2's intrinsic ATPase activity. The authors propose that THO surveys common landmarks in each nuclear mRNP to localize Sub2 for targeted loading of Yra1.

This work establishes a genome-wide function for THO-Sub2 in transcription elongation and mRNP biogenesis that function to prevent the accumulation of transcription-mediated replication obstacles, including R-loops.
Title: Genome-wide function of THO/TREX in active genes prevents R-loop-dependent replication obstacles.
Data suggests that the THO complex/Sub2p function is required to coordinate events leading to the acquisition of export competence at a step that follows commitment to 3'-processing.

Title: The Saccharomyces cerevisiae Sub2 protein suppresses heterochromatic silencing at telomeres and subtelomeric genes.
HSP104 molecules undergoing quality control in THO/sub2 mutants fall into two populations: One that is quickly degraded after transcription induction and another that escapes rapid decay and accumulates in foci associated with HSP104 transcription site.
