UAS drives expression of the complete Snx3 coding sequence in which all three potential PI3P-binding sites (R74, R75 and Y76) are changed to alanines, and with a C-terminal EGFP tag.
Scer\GAL4en.PU-mediated expression of Snx3RRY.Scer\UAS.T:Avic\GFP-EGFP does not rescue the wg protein secretion defect in the posterior compartment of Snx31 wing discs.
