Deletion of ft amino acid residues 4620-5147 (coordinates relative to wild-type, full-length ft sequence). This removes the intracellular domain.
Scer\GAL4Act.PU/ftΔECDΔICD.UAS.Tag:HA fails to rescue ft8/ftG-rv
Scer\GAL4hh-Gal4/ftΔECDΔICD.UAS.Tag:HA fails to rescue ftunspecified
Expression of ftΔECDΔICD.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4Act.PU in ftG-rv/ft8 animals does not rescue eclosion and does not detectably improve hair planar cell polarity defects in the abdomen.
Expression of ftΔECDΔICD.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4hh-Gal4 fails to rescue overgrowth of the posterior compartment of the wing disc in ftunspecified animals.
