UASt drives expression of Tsf2 in which the GPI-modification motif is exchanged for the Mmus\Cd8a transmembrane domain.
Tsf2TM.UAS/Scer\GAL4btl.PS fails to rescue Tsf2ex234
Scer\GAL4btl.PS-mediated expression of Tsf2ΔGPI.Scer\UAS does not rescue the tracheal over-elongation phenotype of Tsf2ex234 embryos.
