There is a subtle overexpression phenotype produced by driving Ptp4EScer\UAS.T:Avic\GFP driven by Scer\GAL4elav.PLu in neurons, in which the longitudinal bundles have a "wavy" appearance.
Expression of Ptp4EScer\UAS.T:Avic\GFP under the control of Scer\GAL4btl.PS completely rescues the tracheal defects of Ptp4E1 Ptp10D1 double mutant embryos.
Scer\GAL4btl.PS-driven Ptp4EScer\UAS.T:Avic\GFP-expression is capable of rescuing the lethality and tracheal phenotypes associated with the Ptp4E1-Ptp10D1 double mutant genotypes. Similarly to ubiquitous overexpression of Ptp4EScer\UAS.T:Avic\GFP driven by Scer\GAL4αTub84B.PL, pan-neural overexpression of Ptp4EScer\UAS.T:Avic\GFP driven by Scer\GAL4elav.PLu does not rescue the lethality in a Ptp4E1-Ptp10D1 background.
