DNA-directed RNA polymerase core subunit RPB5, ABC27, L000001590, L000001679, YBR154C
RNA polymerase subunit ABC27; common to RNA polymerases I, II, and III; contacts DNA and affects transactivation
Saccharomyces cerevisiae (S288c)

PPR2, SII, S-II, TFIIS, P37, L000001476, L000000530, YGL043W
General transcription elongation factor TFIIS; enables RNA polymerase II to read through blocks to elongation by stimulating cleavage of nascent transcripts stalled at transcription arrest sites; maintains RNAPII elongation activity on ribosomal protein genes during conditions of transcriptional stress
Saccharomyces cerevisiae (S288c)

Synthetic Growth Defect

A genetic interaction is inferred when mutations in separate genes, each of which alone causes a minimal phenotype, result in a significant growth defect under a given condition when combined in the same cell.

Publication

Rpb5 modulates the RNA polymerase II transition from initiation to elongation by influencing Spt5 association and backtracking.

Rpb5 is a subunit shared by the three eukaryotic RNA polymerases although its role in transcription remains unclear. It has been proposed that it makes contact with the promoter DNA and to participate in the coordination of the opening/closing of the RNA polymerase II DNA cleft. Here, we report the specific role of Rpb5 in the function of the yeast ... [more]
