UAS regulatory sequences drive expression of an enzyme dead form of Mipp1 (contains the amino acid replacement H67A).
Mipp1H67A.UAS/Scer\GAL4btl.PS fails to rescue Mipp1KO
Decreased number of filopodia per dorsal branch in Mipp1KO/Mipp1KO embryos is not rescued by Mipp1H67A.Scer\UAS expression in the trachea (using Scer\GAL4btl.PS driver).
