UASt regulates expression of Sdc bearing S62A, S79A and S81A mutations (i.e. abrogation of the first three of five canonical heparan sulfate attachment sites), tagged at the C-terminus with GFP.
SdcSG3.UAS.GFP/Scer\GAL4elav.PU rescues Sdc23
Scer\GAL4elav.PU-mediated expression of SdcSG3.Scer\UAS.T:Avic\GFP rescues the Sdc23 ventral midline fascicle cross-over phenotype.
