Scer\GAL4RapGAP1-OK6/brpD2-4.UAS.EGFP fails to rescue brp69/Df(2R)BSC29
Expression of brpD2-4.Scer\UAS.T:Avic\GFP-EGFP under the control of Scer\GAL4Rapgap1-OK6 fails to rescue the formation of T bars at the neuromuscular junction in brp69/Df(2R)BSC29 third instar larvae, although small electron-dense aggregates are often seen localised to the active zone membrane.
