UAS regulatory sequences drive expression of wls tagged with a Tag:HA epitope.
wlsUAS.cBa.Tag:HA/Scer\GAL4en.PU is a suppressor of phenotype of Snx31
Scer\GAL4en.PU-mediated expression of wlsScer\UAS.cBa.T:Ivir\HA1 restores the wg protein secretion defect in the posterior compartment of Snx31 wing discs.
