Insertion of a Tag:PM(hKRAS) (membrane localisation signal) tag at the C-terminal end.
Co-expression of armT:Hsap\MYC,T:Hsap\CAAX and armΔ.Scer\UAS.T:Ivir\HA1 (driven by Scer\GAL4arm.PS) in either a wild-type background, or in a arm2 background, leads to embryos with naked cuticle. When armT:Hsap\MYC,T:Hsap\CAAX and armΔ.Scer\UAS.T:Ivir\HA1 are expressed in a arm1 background however, ectopic denticles are seen.
armTag:MYC,Tag:PM(hKRAS) partially rescues arm043A01
armTag:MYC,Tag:PM(hKRAS) partially rescues arm1
armTag:MYC,Tag:PM(hKRAS) partially rescues arm3
armTag:MYC,Tag:PM(hKRAS) partially rescues arm2
Embryos maternally and zygotically mutant for arm3 have a fragmented cuticle. This cuticle phenotype is completely rescued by armT:Hsap\MYC,T:Hsap\CAAX, but the resulting embryos have a wg null-like phenotype.
Rescues almost to wild type the segment polarity phenotype of embryos that are maternally and zygotically mutant for arm2.
