DBP5

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
Saccharomyces cerevisiae (S288c)
PREY

SLX9

YGR081C
Protein required for pre-rRNA processing; associated with the 90S pre-ribosome and 43S small ribosomal subunit precursor; interacts with U3 snoRNA; deletion mutant has synthetic fitness defect with an sgs1 deletion mutant
Saccharomyces cerevisiae (S288c)

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.
