UASt regulatory sequences drive expression of an inverted repeat.
Expression of CG4928KK102423 under the control of Scer\GAL4da.PU leads to edema (where accumulation of fluid appear both in the abdominal cavity and the Malpighian tubules), increased extracted hemolymph weight, lower concentration of substances dissolved in the hemolymph, reduction of fluid secretion in Malpighian tubules, and a prominent yellow-colored substrate in Malpighian tubules.
