Functional interaction between TFIIB and the Rpb9 (Ssu73) subunit of RNA polymerase II in Saccharomyces cerevisiae.

Nucleic acids research - 1 Jul 1996

Sun Z W, Tessmer A, Hampsey M

Abstract excerpt

Recessive mutations in the SSU71, SSU72 and SSU73 genes of Saccharomyces cerevisiae were identified as either suppressors or enhancers of a TFIIB defect (sua7-1) that confers both a cold-sensitive growth phenotype and a downstream shift in transcription start site selection. The SSU71 (TFG1) gene encodes the largest subunit of TFIIF and SSU72 encodes a novel protein that is essential for cell viability. Here we...
