Stage 16/17 embryos expressing futschEP1419 under the control of Scer\GAL4elav-C155 do not show axonal guidance defects in the ventral nerve cord.

Expression of futschEP1419 under the control of Scer\GAL4D42 has no effect on NMJ bouton number, but does result in longer presynaptic terminals compared with controls.

Expression of futschEP1419 under the control of Scer\GAL4BG380 has no effect on maximum bouton diameter at the larval neuromuscular junction.

Expression of futschEP1419 under the control of Scer\GAL4elav-C155 results in vacuolisation and increased cell death in the brains of 20 day old flies.

Expression of futschEP1419 pre-synaptically, under the control of Scer\GAL4elav-C155 has no significant effect on synaptic mitochondria.

When expression is driven by Scer\GAL4elav-C155 the phenotype is similar to that of Fmr1 loss of function mutants - neuromuscular junction overgrowth with increased synaptic area, branching and bouton number. Neurotransmission at the NMJ is elevated, and in the photoreceptor is depressed.

When expression of futschEP1419 is driven by Scer\GAL4sim.PS, changes in the morphology of individual growth cones is seen, and minor defects in the projection of individual axons are also seen. However these early axonal phenotypes do not lead to defects in the later formation of the central nervous system (CNS) axon pattern.

When futschEP1419 is expressed under the control of Scer\GAL4elav-C155, a slight reduction in average bouton size is seen (about 7.1μm2, compared to 9.1μm2 in wild-type).

The penetrance of the pruning defects observed in class IV dendritic arborizing neurons of pupae expressing par-1HMS00405 under the control of Scer\GAL4ppk.PG is weakly enhanced by co-expression of futschEP1419.

Expression of futschEP1419 under the control of Scer\GAL4BG380 completely suppresses the increase in maximum bouton diameter which is seen at the neuromuscular junction in Aplip1ex larvae.

Expression of futschEP1419 under the control of Scer\GAL4BG380 fails to suppress the defects in axonal transport seen in Aplip1ex larvae.

Expression of futschEP1419 under the control of Scer\GAL4elav-C155 in a spartin1/Df(3R)110 background enhances the number of vacuoles in the brain of 20 day old flies compared to either single mutant.

Co-expression of spartinScer\UAS.T:Ivir\HA1 slightly but significantly suppresses the increased vacuolisation in the brain seen in 20 day old flies expressing futschEP1419 under the control of Scer\GAL4elav-C155.

Expression of futschEP1419 partially suppresses the larval turning and reduced lifespan phenotypes seen when Hsap\TARDBPScer\UAS.T:Avic\GFP-YFP.cEa is expressed under the control of Scer\GAL4D42.

Expression of futschEP1419 partially suppresses the larval turning and reduced lifespan phenotypes seen when Hsap\TARDBPG298S.Scer\UAS.T:Avic\GFP-YFP is expressed under the control of Scer\GAL4D42.

Expression of futschEP1419 fully suppresses the reduction in boutons compared with controls seen when Hsap\TARDBPScer\UAS.T:Avic\GFP-YFP.cEa is expressed under the control of Scer\GAL4D42. The increase in satellite bouton number in the larval NMJ is suppressed to control levels.

Expression of futschEP1419 fully suppresses the reduction in boutons compared with controls seen when Hsap\TARDBPG298S.Scer\UAS.T:Avic\GFP-YFP is expressed under the control of Scer\GAL4D42. The increase in satellite bouton number in the larval NMJ is suppressed to control levels.

Co-expression of futschEP1419 pre-synaptically rescues the synaptic overgrowth phenotype found upon expression of Hsap\LRRK2Scer\UAS.T:Zzzz\FLAG pre-synaptically under the control of Scer\GAL4elav-C155. However, synaptic defects caused by post-synaptic expression of Hsap\LRRK2Scer\UAS.T:Zzzz\FLAG are not suppressed when futschEP1419 is expressed post-synaptically (under the control of Scer\GAL4Mhc.PW).

The abnormal microtubule phenotype seen upon Hsap\LRRK2Scer\UAS.T:Zzzz\FLAG presynaptic expression is rescued by a futschEP1419 expression (both under the control of Scer\GAL4elav-C155).

Neuronal co-expression of futschEP1419 with Hsap\LRRK2Scer\UAS.T:Zzzz\FLAG rescues the mitochondrial distribution phenotype seen upon Hsap\LRRK2Scer\UAS.T:Zzzz\FLAG expression alone.

Expression of futschEP1419 and Rnor\MAP2Scer\UAS.cAa driven by Scer\GAL444 results in frequent axonal swellings and misprojection phenotypes. In 1/5 of neuromeres sensory neurons project their axons in on one of the two commissures across the central nervous system (CNS) midline and fasciculate with their contralateral counterparts, which they never do in wild-type.
