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

NUP145

RAT10, L000001294, YGL092W
Essential protein with distinct roles in two nuclear pore subcomplexes; catalyzes its own proteolytic cleavage in vivo to generate a C-terminal fragment that is a structural component of the Nup84p subcomplex (with roles in NPC biogenesis and localization of genes to the nuclear periphery), and an N-terminal fragment that is one of several FG-nucleoporins within the NPC central core directly responsible for nucleocytoplasmic transport; homologous to human NUP98
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

Dbp5p/Rat8p is a yeast nuclear pore-associated DEAD-box protein essential for RNA export.

Snay-Hodge CA, Colot HV, Goldstein AL, Cole CN

To identify Saccharomyces cerevisiae genes important for nucleocytoplasmic export of messenger RNA, we screened mutant strains to identify those in which poly(A)+ RNA accumulated in nuclei under nonpermissive conditions. We describe the identification of DBP5 as the gene defective in the strain carrying the rat8-1 allele (RAT = ribonucleic acid trafficking). Dbp5p/Rat8p, a previously uncharacterized member of the DEAD-box family ... [more]
