UASt drives expression of a mbc cDNA with a deletion of amino acids 1807 to 1970 (the entire C terminus), and tagged with a Tag:HA epitope.
Scer\GAL4twi.PG-mediated expression of mbcΔ1807.Scer\UAS.T:Ivir\HA1 does not produce muscle phenotypes.
Scer\GAL4twi.PG/mbcΔ1807.UAS.Tag:HA rescues mbcD11.2
Scer\GAL4how-24B/mbcΔ1807.UAS.Tag:HA rescues mbcD11.2/Df(3R)mbc9
Scer\GAL4twi.PG- or Scer\GAL4how-24B-mediated expression of mbcΔ1807.Scer\UAS.T:Ivir\HA1 rescues the mbcD11.2 myoblast fusion defect.
