Expression of ft::Hsap\FAT4^T:SV5\V5 partially rescues the planar cell polarity defects seen in ft⁸/ft^G-rv mutant wings expressing wts^{Scer\UAS.T:Hsap\MYC} under the control of Scer\GAL4^αTub84B.PL. The abdominal hair defects are completely rescued and the reduction in anterior-posterior crossvein distance is partially suppressed.

Expression of one copy of ft::Hsap\FAT4^T:SV5\V5 fails to suppress the wing overgrowth phenotypes seen in ft⁸/ft^G-rv mutant flies expressing one copy of ft^ΔD.T:SV5\V5.

Expression of one copy of ft::Hsap\FAT4^T:SV5\V5 partially suppresses the wing crossvein spacing and hair polarity phenotypes seen in ft⁸/ft^G-rv mutant flies expressing one copy of ft^ΔF.T:SV5\V5.
