UAS regulatory sequences drive expression of a mutated kirre protein that also carries a C-terminal Tag:FLAG-tag. Two putative phosphorylation sites (T810 and T814 ) are mutated.
Scer\GAL4how-24B/kirreT810A.T814A.UAS.Tag:FLAG rescues Df(1)w67k30
Expression of kirreT810A.T814A.Scer\UAS.T:Zzzz\FLAG under the control of Scer\GAL4how-24B restores fusion competent myoblast (FCM) fusion in Df(1)w67k30 mutant embryos.
