Drives larval expression in the wing pouch. Drives adult expression in a subset of cv-c-expressing large field neurons, including lateral fan-shaped neurons ExFl1 and ExFl2.
Adult expression is observed in a cluster of five or six tangential large field neurons with cell bodies located in the dorso-caudal cellular cortex lateral to the calyx of the mushroom body. The axons of these neurons arborize in the rostro-dorsal protocerebrum, near the tip of the α'-lobe of the mushroom body, and dorsally in the fan-shaped body. Additional faint expression is observed in the mushroom bodies.
