A chimeric construct in which amino acids 513 to 774 of sca have been replaced with homologous sequences from Hsap\FGB is expressed under the control of UAS regulatory sequences.
Expression of sca::Hsap\FGBScer\UAS.cLa under the control of Scer\GAL4dpp.blk1 has no effect on wing development. Expression of sca::Hsap\FGBScer\UAS.cLa under the control of Scer\GAL4h-1J3 has no effect on wing vein development.
