UAS regulatory sequences drive expression of a mutant form of WASp step that lacks the PI(4,5)P[[2]] and CDC42 binding domains.
WASpΔBR-H242D.UAS/Scer\GAL4nSyb.PS fails to rescue Df(3R)3450/WASp1
Expression of WASpΔB.H242D.Scer\UAS under the control of Scer\GAL4n-syb.PS fails to rescue the neuromuscular junction overgrowth seen in WASp1/Df(3R)3450 third instar larvae.
