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 early larval lethality or late pupal lethality.
Expression under the control of Scer\GAL4Mef2.PR results in grossly normal larval body wall muscles.
Expression under the control of Scer\GAL4Mef2.PR results in wild-type sarcomeres in the larval body wall muscles.
Expression under the control of Scer\GAL4pnr-MD237 results in lethality or semi-lethality at the pupal stage, depending on the insertion line used.
Expression under the control of Scer\GAL4pnr-MD237 results in the absence of 80-90% of the Scer\GAL4pnr-MD237-expressing area of the notum.
