A 2221 base pair fragment from the flanking non-coding or intronic region of dve is fused upstream of a Drosophila synthetic core promoter (DSCP) followed by sequence encoding a GAL4 driver.
ScerGAL4VT020739 drives expression in a subset of pb-eb-no neurons that innervate the nodulus, but not the ellipsoid body or bridge. Expression overlaps mostly, but not completely with EcollexAGMR12D09.
