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.

Functional interaction between TFIIB and the Rpb2 subunit of RNA polymerase II: implications for the mechanism of transcription initiation.

Chen BS, Hampsey M

The general transcription factor TFIIB is required for accurate initiation, although the mechanism by which RNA polymerase II (RNAP II) identifies initiation sites is not well understood. Here we describe results from genetic and biochemical analyses of an altered form of yeast TFIIB containing an arginine-78 --> cysteine (R78C) replacement in the "B-finger" domain. TFIIB R78C shifts start site selection ... [more]
