SUB2

ATP-dependent RNA helicase SUB2, L000004574, YDL084W
Component of the TREX complex required for nuclear mRNA export; member of the DEAD-box RNA helicase superfamily and is involved in early and late steps of spliceosome assembly; homolog of the human splicing factor hUAP56; relocalizes from nucleus to cytoplasm upon DNA replication stress
Saccharomyces cerevisiae (S288c)
PREY

SUS1

YBR111W-A
Component of both the SAGA histone acetylase and TREX-2 complexes; interacts with RNA polymerase II; involved in mRNA export coupled transcription activation and elongation; involved in post-transcriptional tethering of active genes to the nuclear periphery and to non-nascent mRNP
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

Sus1, a functional component of the SAGA histone acetylase complex and the nuclear pore-associated mRNA export machinery.

Gene expression is a coordinated multistep process that begins with transcription and RNA processing in the nucleus followed by mRNA export to the cytoplasm for translation. Here we report the identification of a protein, Sus1, which functions in both transcription and mRNA export. Sus1 is a nuclear protein with a concentration at the nuclear pores. Biochemical analyses show that Sus1 ... [more]
