DIP-γMI03222/Df(3R)Exel6210 third instar larvae have extra satellite (supernumerary) boutons at the neuromuscular junction (NMJ) compared to wild type and heterozygotes (measured at muscle 4). DIP-γMI03222/Df(3R)Exel6210 third instar larvae show significant increases in miniature excitatory postsynaptic potential (mEPSP) amplitude and frequency (but no difference in evoked responses) compared to controls.
Terminals of R7 photoreceptor cells of yellow ommatidia are bulb-shaped and regularly arranged in layer 6 of the medulla (M6) in DIP-γMI03222/+ adult flies, with less than 10% of terminals having nub-like overshoots that extend deeper into M6; terminals in DIP-γMI03222/Df(3R)Exel6210 adults have irregular shapes, are not lined up in a fixed position along the vertical axis, and show a significant increase (30%) of overshoots, even extending into the M7 layer. DIP-γMI03222/Df(3R)Exel6210 adults have large gaps in medulla layer M6; DIP-γ- and (Dm8-specific driver) Scer\GAL4ort.C2-positive Dm8 neurons are significantly reduced in the optic lobe compared to controls.
Mutant embryos show no visible defects in the CNS axon ladder.

dpr11MI02231/+;DIP-γMI03222/+ transheterozygote third instar larvae have extra satellite (supernumerary) boutons at the neuromuscular junction (NMJ) compared to wild type and heterozygotes (measured at muscle 4) and dpr11MI02231,Df(3R)Exel6210/Df(3R)BSC193,DIP-γMI03222 double mutants show similar increases (non-enhanceable) in NMJ bouton number as dpr11MI02231/Df(3R)BSC193 or DIP-γMI03222/Df(3R)Exel6210 third instar larvae.
DIP-γMI03222/Dadj1E4 transheterozygote third instar larvae have extra satellite boutons at the neuromuscular junction (NMJ) compared to wild type and heterozygotes.
Expression of tkvQ199D.Scer\UAS.T:Ivir\HA1 driven by Scer\GAL4elav.PU in a DIP-γMI03222/+ background leads to extra satellite boutons at the neuromuscular junction (NMJ) of third instar larvae.
DIP-γMI03222/Df(3R)Exel6210 is rescued by Scer\GAL4elav.PU/DIP-γUAS.cCa
Expression of DIP-γScer\UAS.cCa driven by Scer\GAL4elav.PU or Scer\GAL4Mhc.Switch.PO (with RU486 feeding) reduces satellite bouton number at the NMJ of DIP-γMI03222/Df(3R)Exel6210 third instar larvae.
