      ExnEY-Δ50, GluRIIASP16 has NMJ bouton phenotype

      Additional Comments
      Genetic Interactions
      Statement
      Reference

      GluRIIASP16 mutant larvae, also homozygous for an ExnEY-Δ50 allele, show a slight but significant increase in bouton number at the NMJ compared to GluRIIASP16 single mutants.

      GluRIIASP16 mutant larvae, also homozygous for an ExnEY-Δ50 allele, show no difference in average active zone number per NMJ compared to GluRIIASP16 single mutants.
