Expression of Pak3K322A.Scer\UAS.C.T:SV5\V5 under the control of Scer\GAL4twi.PG in a Pak3del background results in an almost complete failure of myoblast fusion in embryos.
Expression of Pak3K322A.Scer\UAS.C.T:SV5\V5 under the control of Scer\GAL4twi.PG in a wild-type background results in minor defects in myoblast fusion in embryos.
