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

The EMBO journal - 1 May 1998

Abstract excerpt

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...
