UASp regulatory sequences drive expression of amino acids 531-1751 of the scrib product (which therefore lacks the leucine-rich repeats (LRR)) containing the Tag:Myr(Src42A) myristoylation sequence at the NH[[2]]-terminus and a COOH-terminal GFP tag.

Co-expression of scribΔLRR.Scer\UAS.P\T.T:Myr6,T:Avic\GFP and scrib<up>ΔPDZs.Scer\UAS.P\T. T:Avic \GFP</up> under the control of Scer\GAL469B fails to rescue the cell polarization and disc overgrowth phenotypes of scrib673/scribird15 transheterozygotes, even when expression levels are increased via raising larvae at 29 oC.
