UASp regulatory sequences drive expression of amino acids 1-1105 of the scrib product (which therefore lacks the third and fourth PDZ domains) containing a COOH-terminal GFP tag.
scribΔPDZ3.4.UASp.GFP/Scer\GAL469B rescues scribird15/scrib673
Expression of scribΔPDZ3.4.Scer\UAS.P\T.T:Avic\GFP under the control of Scer\GAL469B fully rescues the cell polarization and disc overgrowth phenotypes of scrib673/scribird15 transheterozygotes.
