A 974 base pair fragment from the flanking non-coding or intronic region of elav is fused upstream of a Drosophila core synthetic promoter (DSCP) that is followed by sequence encoding a GAL4 driver.
Inhibition (using Ctet\tetXTNT-LC.UAS) of Scer\GAL4GMR37B02 cells significantly reduces larval escape behavior in response to HCl application, compared to controls.
