UASt regulatory sequences drive expression of an inverted repeat.
Expression of CTCFGD5052 under the control of Scer\GAL4nub.PU leads to a decrease in the nuclear size of larval salivary glands.
Depending on the insertion line used, expression under the control of Scer\GAL4Mef2.PR can result in flightless flies or adult/pharate lethality.
Expression under the control of Scer\GAL4Mef2.PR results in grossly normal adult indirect flight muscles.
Expression under the control of Scer\GAL4Mef2.PR results in frayed myofibrils in the adult indirect flight muscles.
Expression under the control of Scer\GAL4Mef2.PR results in sarcomeres with broadened Z-lines in the adult indirect flight muscles.
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 results in the absence of 20-30% of the Scer\GAL4pnr-MD237-expressing area of the notum.
