UAS regulatory sequences drive expression of a fusion protein composed of the GFP tag, the extracellular domain of Bsg (contains the two Ig domains) and the transmembrane and intracellular domains of Rnor\Cd2.
Scer\GAL4elav-C155/Bsgextra.UAS.Tag:M(rCd2),GFP fails to rescue Df(2L)Exel7034/Bsgk13638
Expression of BsgΔextra.T:Rnor\CD2.Scer\UAS.T:Avic\GFP presynaptically (using Scer\GAL4elav-C155) fails to rescue defects in bouton size and number and only poorly rescues bouton growth defects in Bsgk13638/Df(2L)Exel7034 transheterozygotes.
