Expression of diaΔDad.Scer\UAS.P\T.T:Avic\GFP-EGFP under the control of Scer\GAL4sns.PK results in defects in myoblast fusion. Fusion competent myoblasts show a decrease in the volume of F-actin foci and an increase in the frequency of filopodia emanating from an F-actin focus compared to controls.
Expression of diaΔDad.Scer\UAS.P\T.T:Avic\GFP-EGFP under the control of Scer\GAL4en-e16E results in a dramatic increase in the number of filopodia in the epidermal cells. The filopodia are no longer confined to leading edge cells but cover the apical surface of all epidermal cells. In the leading edge cells, filopodia are seen all over the cell, rather than being confined to the leading edge. At the leading edge, the number of filopodia is substantially increased and broad lamellipodia terminating in many filopodia are also seen. Individual filopodia are blunter than in wild type and the lifetime of each filopodium is more than doubled.

Co-expression of enaScer\UAS.T:Avic\GFP and diaΔDad.Scer\UAS.P\T.T:Avic\GFP-EGFP under the control of Scer\GAL4en-e16E in embryos induces protrusions in epidermal cells that are different from those produced by expression of either construct alone. Co-expression results in lamellipodia both at the leading edge and in more ventral epidermal cells, at the expense of filopodia.
Co-expression of Zzzz\actAFP4mito.Scer\UAS.T:Avic\GFP-EGFP under the control of Scer\GAL4en-e16E does not suppress the ability of diaΔDad.Scer\UAS.P\T.T:Avic\GFP-EGFP to induce elevated numbers of filopodia on leading edge cells or on more ventral epidermal cells. The lifetime of the filopodia is still longer than normal in the co-expressing embryos. The number of lamellipodia and lamellipodial area is significantly reduced in the co-expressing leading edge cells compared to wild type.
Expression of diaΔDad.Scer\UAS.P\T.T:Avic\GFP-EGFP in the sensory organ precursor lineage (using Scer\GAL4neur-GAL4-A101) in large homozygous dia5 clones in the leg restores socket cell protrusions and the formation of associated bract cells in the clones.
