UASt regulatory sequences drive expression of an inverted repeat.
Expression under the control of Scer\GAL4Mef2.PR results in early larval lethality.
Expression under the control of Scer\GAL4Mef2.PR results in split larval body wall muscles.
Expression under the control of Scer\GAL4Mef2.PR results in sarcomeres with reduced Z-lines in the larval body wall muscles.
Expression under the control of Scer\GAL4pnr-MD237 results in lethality before the pupal stage.
