Drives expression in the alpha, beta, alpha', beta' and gamma lobes of the mushroom body.
Expression is limited to alpha, beta, and gamma neurons in the adult mushroom body.
Expression is found in only a few alpha'/beta' neurons.
Expression is highest in the mushroom bodies, but is generally widespread.
In third instar larva, expression in antennal disc restricted to groups of cells.
Expression in adult brain primarily in corpora pedunculata (mushroom body).
