Additional Information

Drives expression in dopaminergic and serotonergic neurons, and their precursors.

Scer\GAL4Ddc.PL drives expression very weakly in the ellipsoid and the fan-shaped bodies.

Scer\GAL4Ddc.PL drives expression in a subset of the dopaminergic PPL2ab neurons and in the majority of the PAM neurons (includes MB-M3 and MB-MP1 neurons).

Expression observed in neurons that innervate the mushroom body horizontal lobes and the subsesophageal ganglion.

Expression in the midgut is found in a distinct group of Dh31-expressing enteroendocrine cells located at the junction region of the anterior midgut and the acid-secreting portion of the larval midgut. This junction region occurs at a conspicuous and characteristic U-shaped bend in the gut. These are referred to as the "midgut junction Dh31-expressing cells".

Expression is seen in dopaminergic and serotonergic neurons and their precursors, totalling 9-11 neurons per abdominal half-neuromere by larval stage L1. A precise pattern can be found in FBrf0160715.

Expression is observed in Ddc-expressing neurons.
