UAS regulatory sequences drive expression of a Ptp69D transgene in which the entire extracellular domain of Ptp69D is replaced by a Mmus\Ptprm extracellular domain.
Ptp69DEC.Scer\UAS.T:Mmus\Ptprm driven by Scer\GAL4elav-C155 fails to rescue the Ptp10D1 Ptp69D1 double mutant ventral nerve cord phenotype.
