Scer\GAL4twi.PG-mediated expression of mbcNPxxP.Δ1807.Scer\UAS.T:Ivir\HA1 does not produce muscle phenotypes.
Expression of mbcNPxxP.Δ1807.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4sns.PK restores fusion in mbcD11.2 embryos and a wild-type somatic muscle pattern is formed.
Scer\GAL4twi.PG- or Scer\GAL4how-24B-mediated expression of mbcNPxxP.Δ1807.Scer\UAS.T:Ivir\HA1 rescues the mbcD11.2 myoblast fusion defect.
