Reporter expression is observed in embryos in the salivary gland, amnioserosa, and gut, recapitulating aspects of the endogenous in situ pattern of GlcAT-P. In larvae, expression is observed in the tracheal system, in a subset of neurons and glia in the larval brain and ventral nerve cord, as well as in Kenyon cells. Expression is observed two ventral nerve cord neurons per neuromere that were identified as VUM motorneurons.
