UASt regulatory sequences drive expression of an inverted repeat of mtg sequences, which consists of a genomic fragment containing sequence from exons 5 to 7 and a cDNA fragment containing sequence from exons 5 to 6.
Animals expressing mtgdsRNA.Scer\UAS under the control of Scer\GAL4elav-C155 in a mtg1/+ background show reduced larval and adult viability, although substantial numbers of viable adults do survive.
