UASt sequences drive expression of Antp in which the residues 288-378 (linker, homeodomain and C-terminus) have been replaced by the equivalent regions of Ubx isoform Ia (residues 244-380).
embryonic/first instar larval cuticle, with Scer\GAL4arm.PS
Keilin organ, with Scer\GAL4arm.PS
ventral denticle belt, with Scer\GAL4arm.PS
Embryonic/first instar larval cuticle phenotype due to Antp::UbxAAUA.Scer\UAS; Scer\GAL4arm.PS : 80% lack keilin's organs; denticle belt phenotype is mostly like that due to due to UbxIa.Scer\UAS; Scer\GAL4arm.PS.
