UASt regulates expression of Sdc bearing a S62A mutation (i.e. abrogation of the first of five canonical heparan sulfate attachment sites), tagged at the C-terminus with GFP.
Scer\GAL4elav.PU/SdcSG1.UAS.GFP rescues Sdc23
Scer\GAL4elav.PU-mediated expression of SdcSG1.Scer\UAS.T:Avic\GFP rescues the Sdc23 ventral midline fascicle cross-over phenotype.
