UASt regulatory sequences drive expression of mib2 (EST LP14687 from the BDGP) lacking the ZZ domain (nt 238-345).
Scer\GAL4kirre-rP298-G4/mib2ΔZZ.UAS rescues mib21
The expression of mib2ΔZZ.Scer\UAS under the control of Scer\GAL4kirre-rP298-G4 rescues both the somatic muscle defects and the visceral muscle defects, and associated bloated midgut phenotype, exhibited by mib21 homozygous embryos.
