Scer\GAL4ptc.PU-mediated expression of FhosΔB.Scer\UAS.T:Avic\GFP-EGFP results in significant elevation of F-actin levels and epithelial cell constriction leading to apical invaginations in wing discs.
Expression of FhosΔB.Scer\UAS.T:Avic\GFP-EGFP in larval salivary glands dramatically reorganizes the basal actin cytoskeleton to long and thick bundles. Overall gland morphology is also affected, with multiple cyst-like lumina present instead of the single lumen of wild type glands.
