YRA1

SHE11, RNA-binding protein YRA1, L000002959, L000002873, YDR381W
Nuclear polyadenylated RNA-binding protein; required for export of poly(A)+ mRNA from the nucleus; proposed to couple mRNA export with 3' end processing via its interactions with Mex67p and Pcf11p; interacts with DBP2; inhibits the helicase activity of Dbp2; functionally redundant with Yra2p, another REF family member

NUP1

FG-nucleoporin NUP1, L000001288, YOR098C
FG-nucleoporin component of central core of the nuclear pore complex; contributes directly to nucleocytoplasmic transport and maintenance of thenuclear pore complex (NPC) permeability barrier; possible karyopherin release factor that accelerates release of karyopherin-cargo complexes after transport across NPC; both NUP1 and NUP60 are homologous to human NUP153
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

The mRNA export machinery requires the novel Sac3p-Thp1p complex to dock at the nucleoplasmic entrance of the nuclear pores.

Yra1p and Sub2p are components of the TREX complex, which couples transcription elongation with nuclear export of mRNAs. Here, we report a genetic interaction between Yra1p and a conserved protein Sac3p, which previously was found to interact with Sub2p. In vivo, Sac3p forms a stable complex with Thp1p, which was reported to function in transcription elongation. In addition, Sac3p binds ... [more]
