RAT8, ATP-dependent RNA helicase DBP5, L000003292, YOR046C
Cytoplasmic ATP-dependent RNA helicase of the DEAD-box family; involved in mRNA export from the nucleus, remodeling messenger ribonucleoprotein particles (mRNPs), with ATPase activity stimulated by Gle1p, IP6 and Nup159p; involved in translation termination along with Sup45p (eRF1); role in the cellular response to heat stress

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.
Publication
Synthetic genetic array analysis in Saccharomyces cerevisiae provides evidence for an interaction between RAT8/DBP5 and genes encoding P-body components.
Coordination of the multiple steps of mRNA biogenesis helps to ensure proper regulation of gene expression. The Saccharomyces cerevisiae DEAD-box protein Rat8p/Dbp5p is an essential mRNA export factor that functions at the nuclear pore complex (NPC) where it is thought to remodel mRNA/protein complexes during mRNA export. Rat8p also functions in translation termination and has been implicated in functioning during ... [more]

Throughput
- High Throughput|Low Throughput
Ontology Terms
- phenotype: inviable (APO:0000112)
Additional Notes
- High Throughput: DBP5 is also known as RAT8. An SGA analysis was carried out using the temperature sensitive rat8-2 allele as the query.
- Low Throughput: Random spore analysis was performed to validate gene deletions that showed a synthetic interaction with rat8-2.
