UASt regulatory sequences drive expression of a mir-7 "sponge" sequence, which consists of ten repetitive mir-7 complementary sequences with mismatches at positions 9-12 separated by a variable four-nucleotide linker. The sponge sequence is inserted into 3'UTR sequence downstream of the EGFP coding region, to enhance stability.
Expression of Avic\GFPEGFP.Scer\UAS-mir-7SP under the control of the eye specific driver Scer\GAL4ey.PH has no detectable effect on overall adult eye morphology.
