| Dataset |
A set of transgenic insertion stocks derived by TE mobilization using the P-element construct P{EP}. The P{EP} construct construct carries a w[+mC] mini-white visible marker, Scer\UAS binding sites for the Scer\GAL4 transcriptional regulator, and bacterial sequences that allow plasmid rescue. The GAL4-UAS system allows regulated expression
of genes proximate to the site of the insertion: genes properly oriented with respect to the Scer\UAS sequences can be conditionally expressed via transgene-derived Scer\GAL4 activity.
Insertion lines from this collection were mapped and assessed for inclusion in the Gene Disruption Project collection; flanking
sequence data were submitted to GenBank.

Statement
Reference
Animals derived from homozygous faf[EP381] females mated to dpp[hr4]/+ males show strong lethality (only 26% of the expected number survive). The embryos have a ventralised cuticle phenotype.
Neural expression of fafEP381, under the control of Scer\GAL4elav-C155 leads to an increased number of synaptic boutons and branches and an increased synaptic span.
wnd1/wnd2 mutants suppress the synapse phenotype of fafEP381, under the control of Scer\GAL4elav-C155.
Expression of faf[EP381] under the control of Scer\GAL4[GMR.PF] at room temperature results in smooth glassy eyes (due to fusion of ommatidia) that are also moderately reduced in size.
The faf[EP381] (Scer\GAL4[GMR.PF]) overexpression phenotype is strongly enhanced by co-expression with pbl[EP3415] as the ommatidial field is reduced to approximately 30% of normal in Scer\GAL4[GMR.PF]-driven pbl[EP3415] and faf[EP381] flies.
The synergistic effect of pbl[EP3415] and faf[EP381] can be overcome by co-expression with Hsap\UBE3A[Scer\UAS.cRa] (all under the control of Scer\GAL4[GMR.PF].
Co-expression of Hsap\UBE3A[Scer\UAS.cRa] with faf[EP381] (both under the control of Scer\GAL4[GMR.PF]) partially suppresses the smooth eye phenotype induced by expression of faf[EP381] alone.
Expression of fafEP381 under the control of Scer\GAL4Tab2-201Y results in misguidance and mushroom body overgrowth phenotypes.
pnrMD237/+ adults expressing fafEP381 under the control of Scer\GAL4pnr-MD237 have a slight cleft in the abdominal dorsal midline and a reduced scutellum.
Flies expressing fafEP381 under the control of Scer\GAL4ap-md544 have ectopic bristles on the dorsal surface of the wing blade.
When fafEP381 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 fafEP381, 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.
In the dorsal muscle region of mutant larvae expressing fafEP381 under the control of Scer\GAL4elav-C155, the synapses at the second branchpoint and terminal arbor have abnormal structures, with a spray of extra branches emanating
from the terminal arbor.
Mutant larvae expressing fafEP381 under the control of Scer\GAL4elav-C155 have ISN neuron pathfinding defects. Mutant larvae expressing fafEP381 under the control of Scer\GAL4elav-C155 have excessive or ectopic synapses. Mutant larvae expressing fafEP381 under the control of Scer\GAL4elav-C155 have reduced or abnormal synapses. They have abnormal ISN synaptic branches and a reduced number of boutons.
Expression of fafEP381 under the control of Scer\GAL4sca-537.4 results in loss of external support cells of the scutellar and dorsocentral macrochaetae without loss of the sheath cell.
Shafts with a branched tip are seen. On the abdomen, dot-like shaft morphology is seen.
