UASt regulatory sequences drive expression of all but the N-terminal methionine of Pten isoform 2, fused at its N-terminal to EGFP.
Pten2.UAS.EGFP/Scer\GAL4GMR.PF rescues Pten1
Expression of Pten2.Scer\UAS.T:Avic\GFP under the control of Scer\GAL4GMR.PF is able to suppress all rhabdomeric phenotypes in Pten1 mutant eyes.
