UASt regulatory sequences drive expression of a constitutively active form of yki in which the serine at amino acid 168 has been replaced by alanine.
visible, with Scer\GAL4GMR.PU
eye, with Scer\GAL4GMR.PU
Expression of ykiS168A.Scer\UAS.cIa under the control of Scer\GAL4GMR.PU results in eye overgrowth.
