A genetic screen for modifiers of drosophila Src42A identifies mutations in Egfr, rolled and a novel signaling gene.

Abstract excerpt

Drosophila Src42A, a close relative of the vertebrate c-Src, has been implicated in the Ras-Mapk signaling cascade. An allele of Src42A, Su(Raf)1, dominantly suppresses the lethality of partial loss-of-function Raf mutations. To isolate genes involved in the same pathway where Src42A functions, we carried out genetic screens for dominant suppressor mutations that prevented Su(Raf)1 from suppressing Raf....
