UASt sequences drive expression of Antp in which the homeodomain (residues 296-356) and C-terminus (357-378) have been replaced with equivalent regions of Ubx isoform Ia (residues 285-380).
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::UbxAAUU.Scer\UAS; Scer\GAL4arm.PS : 24% lack keilin's organs; denticle belt phenotype is mostly like that due to AntpScer\UAS.cMa; Scer\GAL4arm.PS.
