UASt regulates expression of Sdc bearing S62A, S79A, S81A, S109A and S194A mutations (i.e. abrogation of all five canonical heparan sulfate attachment sites), tagged at the C-terminus with GFP.
Scer\GAL4elav.PU/SdcSG5.UAS.GFP rescues Sdc23
Scer\GAL4elav.PU-mediated expression of SdcSG5.Scer\UAS.T:Avic\GFP rescues the Sdc23 ventral midline fascicle cross-over phenotype.
