The expression of Vps35Scer\UAS.cIa under the control of Scer\GAL4da.G32 in a Vps351/Vps35MH20 transheterozygous background does not affect the number of active zones in third instar larval neuromuscular junction boutons, as compared to controls.
The expression of Vps35Scer\UAS.cIa under the control of Scer\GAL4da.G32 rescues the prepupal lethality of Vps351/Vps35MH20.
In the third instar larval neuromuscular junction of Vps351/Vps35MH20 transheterozygotes, the decreased pool of synaptic vesicles, the associated reciprocal increased number and increased size of synaptic boutons, the decreased endocytosis and the subtle ultrastructural defects of the subsynaptic reticulum are rescued by the expression of Vps35Scer\UAS.cIa under the control of Scer\GAL4da.G32; the increased miniature excitatory junction potential amplitude and the decreased excitatory junction potential amplitude under high stimulation conditions are rescued by the expression of Vps35Scer\UAS.cIa, but not Vps35D647N.Scer\UAS, under the control of either Scer\GAL4da.G32, Scer\GAL4Toll-6-D42 or Scer\GAL4Mhc.PK.
The expression of Vps35Scer\UAS.cIa under the control of Scer\GAL4ple.PF rescues the decreased sleep bouts displayed by Vps351 heterozygous adults.
In Vps35MH20 heterozygotes, the expression of Vps35Scer\UAS.cIa under the control of Scer\GAL4da.G32 rescues the decreased adult lifespan and the increased number of type Ib synaptic boutons in third instar larval neuromuscular junction; the expression of Vps35Scer\UAS.cIa under the control of Scer\GAL4ple.PF rescues the decreased spontaneous synaptic activity of adult dendritic arborizing neurons.
