CTF15, DNA-directed RNA polymerase II subunit RPB4, B32, L000001678, YJL140W
RNA polymerase II subunit B32; forms dissociable heterodimer with Rpb7p; Rpb4/7 dissociates from RNAPII as Ser2 CTD phosphorylation increases; Rpb4/7 regulates cellular lifespan via mRNA decay process; involved in recruitment of 3'-end processing factors to transcribing RNAPII complex, export of mRNA to cytoplasm under stress conditions; also involved in translation initiation

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
Mediator subunits and histone methyltransferase Set2 contribute to Ino2-dependent transcriptional activation of phospholipid biosynthesis in the yeast Saccharomyces cerevisiae.
To activate eukaryotic genes, several pathways which modify chromatin and recruit general factors of the transcriptional machinery are utilized. We investigated the factors required for activation of yeast phospholipid biosynthetic genes, depending on activator protein Ino2 which binds to the inositol/choline-responsive element (ICRE) upstream promoter motif together with its partner protein Ino4. We used a set of 15 strains each ... [more]
