RPB4
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
Members of the SAGA and Mediator complexes are partners of the transcription elongation factor TFIIS.
TFIIS, an elongation factor encoded by DST1 in Saccharomyces cerevisiae, stimulates transcript cleavage in arrested RNA polymerase II. Two components of the RNA polymerase II machinery, Med13 (Srb9) and Spt8, were isolated as two-hybrid partners of the conserved TFIIS N-terminal domain. They belong to the Cdk8 module of the Mediator and to a subform of the SAGA co-activator, respectively. Co-immunoprecipitation ... [more]
