UAS regulatory sequences drive expression of amino acids 1-794 (corresponding to the extracellular domain of the PEST-negative form) of a truncated Fas2 containing YFP inserted into the C-terminal end of its transmembrane domain.
Expression of Fas2extra.UAS.YFP under the control of Scer\GAL4Uro.PT leads to longer and aberrant microvilli and a significant increase in the stimulated rate of fluid secretion in renal tubules when compared to control adults.
