UASt regulatory sequences drive expression of an inverted repeat.
Expression of Bap55GD11955 under the control of Scer\GAL4ey.PU leads to small eyes.
Expression under the control of Scer\GAL41407 results in an increased number and size of GFP-positive aggregates within neuroblast lineage cells in the larval brain compared to controls (these aggregates may indicate cell death or a disturbance of internal cellular structures).
Expression of Bap55GD11955 under the control of the cardioblast-specific Scer\GAL4tin.CΔ4 driver results in viable flies or partial lethality, depending on the particular P{GD11955} insertion line used.
Depending on the insertion line used, expression under the control of Scer\GAL4Mef2.PR can result in viable flies or adult/pharate lethality.
Expression under the control of Scer\GAL4pnr-MD237 results in lethality before the pupal stage 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.
