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
Stimulation of transcription by mutations affecting conserved regions of RNA polymerase II.
Mutations that increase the low-level transcription of the Saccharomyces cerevisiae HIS4 gene, which results from deletion of the genes encoding transcription factors BAS1, BAS2, and GCN4, were isolated previously in SIT1 (also known as RPO21, RPB1, and SUA8), the gene encoding the largest subunit of RNA polymerase II (RNAPII). Here we show that sit1 substitutions cluster in two conserved regions ... [more]
