UASt regulatory sequences drive expression of an inverted repeat.
Depending on the insertion line used, expression under the control of Scer\GAL4Mef2.PR can result in viable flies or late larval lethality.
Expression under the control of Scer\GAL4pnr-MD237 may result in semi-lethality, depending on the insertion line used.
Expression under the control of Scer\GAL4pnr-MD237 may result in an enlarged notum, depending on the insertion line used.
