UASt regulatory sequences drive expression of an internally deleted form of vari that lacks the PDZ domain (lacks amino acid residues 158-259, coordinates according to GB:AAN11089.3). The protein is tagged with Tag:HA.
variΔPDZ.UAS.Tag:HA/Scer\GAL4elav.PLu fails to rescue vari327
Expression of variΔPDZ.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4elav.PLu does not rescue the axon guidance defects observed in intersegmental nerve b motor axons of vari327 mutant embryos.
