UAS regulatory sequences drive expression of a mutant form of Pak3 which contains the amino acid replacements H29L and H31L. The protein is tagged at the N-terminal end with Tag:V5.
Scer\GAL4twi.PG/Pak3H29L.H31L.UAS.Tag:V5 fails to rescue Pak3del
Expression of Pak3H29L.H31L.Scer\UAS.T:SV5\V5 under the control of Scer\GAL4twi.PG fails to rescue the myoblast fusion defect seen in zygotically mutant Pak3del embryos.
