The FRT cassette has been excised, juxtaposing αTub84B promoter sequences with an activated form of Hsap\RAF1 (which contains a 305 amino acid N-terminal truncation), tagged with a myristoylation sequence (Tag:Myr(Src64B)).
Clones of Hsap\RAF1Δ305.αTub84B.T:Myr1 in the adult abdomen do not show any consistent alterations of normal polarity.
Expression of Hsap\RAF1Δ305.αTub84B.T:Myr1 in the eye disc induces ectopic photoreceptor differentiation just anterior to the morphogenetic furrow.
