In adult, expressed in the principal (type I) cells of the Malpighian tubules, highest expression in main segment, lower levels in the initial segment and the transitional segment. Expression not restricted to Malpighian tubules.
Ubiquitous expression observed, with particularly strong expression in epithelial tissue. Expression is detected in the Malpighian tubules, posterior adult hindgut, salivary glands, and cuticular sensillae; the uterus and female accesory glands also stain.
In wandering third instar larva, high levels of expression in foregut, midgut and Malpighian tubules; moderate levels in hindgut, salivary glands and gonad.
