UASt regulatory sequences drive expression of a mutated form of Nlg3; carries the D397R amino acid replacement known to disrupt the interaction between Nlg3 and Neurexin.
The expression of Nlg3D397R.UAS under the control of Scer\GAL4how-24B induces a severe decrease in the number of boutons at the third instar larval neuromuscular junction, as compared to controls.
