Pan-neuronal expression of the membrane-bound tutlHL01565.Scer\UAS isoform under the control of Scer\GAL4elav-C155 does not generate a phenotype.
Overexpression of tutlHL01565.Scer\UAS under the control of Scer\GAL4sca-109-68, Scer\GAL4how-24B or Scer\GAL4G14 produces branching of the ISNd nerve, stalling of motor nerves, with some nerves, such as the transverse nerve, innervating muscles that are not their normal targets.
Overexpression of tutlHL01565.Scer\UAS in a wild-type background using the retina-specific Scer\GAL4GMR.PF produces neuronal defects in that many retinal axons stall before reaching their targets and some sprout extra axonal processes.
Scer\GAL4repo/tutlHL01565.UAS fails to rescue tutlex383
Scer\GAL4repo/tutlHL01565.UAS fails to rescue Df(2L)ed-dp/tutlex383
Post-mitotic neuronal expression of tutlHL01565.Scer\UAS under the control of either Scer\GAL4sim.PS or Scer\GAL4elav-C155 fully rescues the midline crossing defects found in tutlex383 and tutlex383/Df(2L)ed-dp mutants. Expression under the control of Scer\GAL4repo does not rescue the phenotype, indicating that expression near the midline is important for rescue.
