A 2367 base pair fragment from the flanking non-coding or intronic region of DIP-δ is fused upstream of a Drosophila synthetic core promoter (DSCP) followed by sequence encoding a GAL4 driver.
ScerGAL4VT026020 drives expression in a subset of cold activated thermosensitive antennal lobe projection neurons. These fasciculate with the medial antennal lobe tract and terminate in the lateral horn and mushroom body.
