UASt regulatory sequences drive expression of arm tagged at the N-terminus with Tag:NES(oPKI) (a nuclear export sequence) and tagged at the C-terminus with 5 copies of Tag:MYC.
Embryos expressing armScer\UAS.T:Hsap\MYC,T:Ocun\nes under the control of Scer\GAL4e22c sometimes show a partial loss of denticle belts along the ventral midline and occasionally have ectopic denticle laterally.
armUAS.Tag:MYC,Tag:NES(oPKI)/Scer\GAL4e22c partially rescues arm2
The segment polarity phenotype of embryos maternally and zygotically mutant for arm2 is substantially rescued by armScer\UAS.T:Hsap\MYC,T:Ocun\nes expressed under the control of Scer\GAL4e22c.
