Reference

Drives expression in the hindgut and Malpighian tubules at embryonic and larval stages; expression is also driven in other components of the gut, including the midgut, proventriculus, and larval enteroendocrine cells.

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 also observed in the proventriculus.
