UASt regulatory sequences drive expression of aop that has been mutated to increase the affinity of the aop SAM domain for self-association; the changes are A93E and G96R. Each mutation converts the wild-type aop residue to the equivalent residue found in the orthologous human ETV6 gene (HGNC:3495).
eye, with Scer\GAL4GMR.PU
Expression from two copies of aopSY2.UAS under the control of Scer\GAL4GMR.PU induces a severe rough eye phenotype with severe loss of pigmentation; expression from one copy does not induce obvious defects.
