DBP2
DEAD-box ATP-dependent RNA helicase DBP2, L000000493, YNL112W
ATP-dependent RNA helicase of the DEAD-box protein family; has a strong preference for dsRNA; interacts with YRA1; required for the assembly of Yra1p, Nab2p and Mex67p onto mRNA and formation of nuclear mRNP; involved in mRNA decay and rRNA processing; may be involved in suppression of transcription from cryptic initiation sites

RRP6
exosome nuclease subunit RRP6, L000003540, YOR001W
Nuclear exosome exonuclease component; has 3'-5' exonuclease activity that is regulated by Lrp1p; involved in RNA processing, maturation, surveillance, degradation, tethering, and export; role in sn/snoRNAs precursor degradation; forms a stable heterodimer with Lrp1p; has similarity to E. coli RNase D and to human PM-Sc1 100 (EXOSC10); mutant displays reduced transcription elongation in the G-less-based

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.

The DEAD-box RNA Helicase Dbp2 Connects RNA Quality Control with Repression of Aberrant Transcription.
DEAD-box proteins are a class of RNA-dependent ATP hydrolysis enzymes that rearrange RNA and RNA:protein (RNP) structures. In an effort to characterize the cellular function of individual DEAD-box proteins, our laboratory has uncovered a previously unrecognized link between the DEAD-box protein Dbp2 and regulation of transcription in Saccharomyces cerevisiae. Herein, we report that Dbp2 is a double-stranded RNA specific ATPase ... [more]
