Additional Information

Drives expression in reticular neuropil associated glial cells.

The larval neuropil glial cells are Gs2-positive and comprise Scer\GAL4alrm.PD-positive, pros-positive and Scer\GAL4NP6520-positive, pros-negative subsets.

Scer\GAL4alrm.PD drives expression in a subset of distal medulla astrocyte-like glial cells with processes to medulla layer M7.
