Expression of fafEP3520 under the control of Scer\GAL4Ccap.PP results in subtle defects in small portions of the central nervous system arbor in larvae.
Expression of fafEP3520 under the control of Scer\GAL4Ccap.PP results in the loss of adult-specific neurite projections.
When fafEP3520 is driven by Scer\GAL4elav-C155, a marked expansion in the size and complexity is seen in the synapses. There is an increase in both the number of synaptic boutons and in the synaptic span. There is also an increase in the number of synaptic branches. When the evoked excitatory junctional potentials (EJPs) of fafEP3520, Scer\GAL4elav-C155 embryos are examined, a marked reduction is seen in their amplitudes. A large decrease in quantal content is also seen, and the frequency of spontaneous mEJPs is also reduced.
