Drives expression in larval olfactory receptor neuron Or33b/Or47a, which projects to larval antennal lobe glomerulus 33b/47a; adult olfactory receptor neuron Or47a, which projects to antennal lobe glomerulus DM3; and antennal basiconic sensillum ab5.
Sensory neurons expressing Or47a project into the DM3 antennal glomerulus.
Axons of Or47a-expressing neurons project to the DM3 glomerulus.
Expression of Or47a is observed in 20 lateral distal neurons. These neurons project axons that converge on a single bilaterally symmetric glomerulus located at the dorsal medial limit of the antennal lobe.
