rgγ1 mutants display abnormal type I bouton morphology: changes in shape, fusion of boutons. Size of type I boutons remains unchanged but their number is significantly decreased.
rgγ1 mutants show altered synaptic transmission at larval neuromuscular junctions with abnormally large excitatory junctional potentials.
rgγ1 mutants show decreased frequency of peristaltic contractions, decreased speed of movement and are more likely to be in a curled position.
Moderate rough eye phenotype.
