BAIT
NUP84
L000003137, YDL116W
Subunit of the Nup84p subcomplex of the nuclear pore complex (NPC); contributes to nucleocytoplasmic transport and NPC biogenesis; also plays roles in several processes that may require localization of genes or chromosomes at the nuclear periphery, including double-strand break repair, transcription and chromatin silencing; homologous to human NUP107

SPT4
transcription elongation factor SPT4, L000002030, YGR063C
Component of the universally conserved Spt4/5 complex (DSIF complex); the complex has multiple roles in concert with RNA polymerases I and II, including regulation of transcription elongation, RNA processing, quality control, and transcription-coupled DNA repair; Spt4p also localizes to kinetochores and heterochromatin and affects chromosome dynamics and silencing; required for transcription through lengthy trinucleotide repeats in ORFs or non-protein coding regions

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
A novel assay identifies transcript elongation roles for the Nup84 complex and RNA processing factors.
To clarify the role of a number of mRNA processing factors in transcription elongation, we developed an in vivo assay for direct analysis of elongation on chromatin. The assay relies on two substrates containing two G-less cassettes separated by either a long and GC-rich or a short and GC-poor DNA sequence (G-less-based run-on (GLRO) assay). We demonstrate that PAF, THSC/TREX-2, ... [more]
