Ubi-p63E promoter sequences drive expression of mys coding sequences carrying a predicted deactivating mutation in the distal NPxY motif of the cytoplasmic domain (carries the amino acid replacement N840A, predicted to disrupt the binding of a subset of signaling molecules that are required for inside-out integrin activation).
mysN840A.EYFP.Ubi-p63E partially rescues mys11
Expression of mysN840A.T:Avic\GFP-EYFP.Ubi-p63E partially rescues both the germband retraction and dorsal closure phenotypes found in mys11 embryos.
The mysN840A.T:Avic\GFP-EYFP.Ubi-p63E transgene partially rescues the muscle detachment phenotype seen in mys11 embryos. Although myotendinous junction length appears fully rescued in these animals, there is a mild but significant reduction in myotendinous area compared to wild-type.
