UAS regulatory sequences drive expression of mature spz5 (the signal peptide plus cystine knot domains).
neuromuscular junction | larval stage, with Scer\GAL4Toll-6-D42
presynaptic active zone | larval stage, with Scer\GAL4Toll-6-D42
The expression of spz5CK.UAS under the control of Scer\GAL4Toll-6-D42 leads to a significant increase in the number of active zones at the larval NMJ, as compared to controls.
