A Mmus\Ctnnb1 cDNA is expressed under the control of UASt regulatory sequences.
Overexpression of Mmus\CatnbScer\UAS.cWa under the control of Scer\GAL4Bx-MS1096 results in ectopic wing vein formation and loss of both anterior and posterior margin bristles.
Scer\GAL4arm.PS/Mmus\Ctnnb1UAS.cWa is a suppressor of embryonic/first instar larval cuticle phenotype of arm2
Mmus\CatnbScer\UAS.cWa expressed under the control of Scer\GAL4arm.PS partially rescues hemizygous arm2 embryos derived from homozygous arm2 female germline clones. Expression of Mmus\CatnbScer\UAS.cWa under the control of Scer\GAL4arm.PS in arm2/+ embryos derived from homozygous arm2 female germline clones leads to a weak segment polarity phenotype (extra denticles in naked cuticle regions).
