UAS regulatory sequences drive expression of the extracellular and transmembrane domains of sev (Tag:M(sev)) fused to the N-terminus of arm.
Ubiquitous expression of armScer\UAS.T:sev-TM in embryos using Scer\GAL4unspecified does not cause a cuticle phenotype.
Scer\GAL4da.G32/armUAS.Tag:M(sev) partially rescues arm2
Scer\GAL4arm.PS/armUAS.Tag:M(sev) fails to rescue arm4, armS12.Tag:MYC
Scer\GAL4arm.PS/armUAS.Tag:M(sev) fails to rescue arm4, armS6.Tag:MYC
The "lawn of denticles" cuticle phenotype seen in embryos carrying armS6.T:Hsap\MYC in an arm4 background is not rescued by ubiquitous expression of armScer\UAS.T:sev-TM using Scer\GAL4arm.PS. The "lawn of denticles" cuticle phenotype seen in embryos carrying armS12.T:Hsap\MYC in an arm4 background is not rescued by ubiquitous expression of armScer\UAS.T:sev-TM using Scer\GAL4arm.PS. The "lawn of denticles" cuticle phenotype seen in arm2 embryos is substantially rescued by ubiquitous expression of armScer\UAS.T:sev-TM using Scer\GAL4da.G32 (stripes of naked cuticle are restored).
