UAS regulatory sequences drive expression of the nau coding region in antisense orientation.
presumptive embryonic/larval muscle system, with Scer\GAL4how-24B, Scer\GAL4twi.PG
Expression of naua.Scer\UAS under the control of both Scer\GAL4how-24B and Scer\GAL4twi.PG disrupts muscle formation in embryos.
