Amino acid replacement: C935S.
Amino acid replacement: C1020S.
Expression of two copies of mib2C935S-C1020S.Scer\UAS under the control of Scer\GAL4Mef2.PR does not result in myoblast fusion defects in embryos.
Scer\GAL4how-24B/mib2C935S-C1020S.UAS partially rescues mib21
Expression of mib2C935S-C1020S.Scer\UAS under the control of Scer\GAL4how-24B does not rescue the myoblast fusion defect of mib21 embryos, but rescues the other embryonic phenotypes (detachment phenotype, sarcomeric organisation and, to a large extent, the visceral muscle defects, since all but the first gut constriction are formed).
