THO2
LDB5, RLR1, ZRG13, L000002589, YNL139C
Subunit of the THO complex; THO is required for efficient transcription elongation and involved in transcriptional elongation-associated recombination; required for LacZ RNA expression from certain plasmids

CTK1
cyclin-dependent serine/threonine protein kinase CTK1, L000000432, YKL139W
Catalytic (alpha) subunit of C-terminal domain kinase I (CTDK-I); phosphorylates both RNA pol II subunit Rpo21p to affect transcription and pre-mRNA 3' end processing, and ribosomal protein Rps2p to increase translational fidelity; required for H3K36 trimethylation but not dimethylation by Set2p; similar to the Drosophila dCDK12 and human CDK12 and probably CDK13

Synthetic Lethality
A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.

Nuclear mRNA surveillance in THO/sub2 mutants is triggered by inefficient polyadenylation.
The yeast THO complex and the associated RNA helicase Sub2p are important mRNP maturation factors. Transcripts produced in THO/sub2 mutants are subject to degradation by a surveillance mechanism that involves the nuclear RNA exosome. Here we show that inefficient polyadenylation forms the basis of this accelerated mRNA decay. A genetic screen reveals extensive interactions between deletions of THO subunits and ... [more]
