hide Detailed Description
Statement
Reference
Expression of ATP7[Scer\UAS.T:Zzzz\FLAG] under the control of Scer\GAL4[pnr-MD237] results in a hypopigmentation phenotype in the adult dorsal cuticle of the thorax and abdomen (in the domain of Scer\GAL4 expression). Expression of ATP7[Scer\UAS.T:Zzzz\FLAG] under the control of Scer\GAL4[GMR.PFa] has no effect on the eye.
Expression of ATP7[Scer\UAS.T:Zzzz\FLAG] under the control of Scer\GAL4[pnr-MD237] causes hypopigmentation and loss of sensory bristles in the pnr region, and reduced thoracic width in adult flies.
ATP7[Scer\UAS.T:Zzzz\FLAG]; Scer\GAL4[Act5C.PI] grown on copper deficient medium have reduced abdominal pigmentation. This phenotype is largely rescued by adding back copper to the medium, but not by supplementing the copper deficient medium with iron or zinc. ATP7[Scer\UAS.T:Zzzz\FLAG]; Scer\GAL4[pnr-MD237] adults have a non pigmented stripe running down the midline of the notum. They also have a cleft in the thorax, reduction in the scutellum and variable loss of thoracic bristles. This loss of pigmentation is independent of dietary copper levels. ATP7[Scer\UAS.T:Zzzz\FLAG]; Scer\GAL4[tracheal] animals die as late larvae or early pupae. ATP7[Scer\UAS.T:Zzzz\FLAG]; Scer\GAL4[ptc-559.1] adults show reduction of the scutellum and partial or complete loss of scutellar bristles.

Co-expression of either Ctr1A[Scer\UAS.T:Zzzz\FLAG] or Ctr1B[Scer\UAS.T:Zzzz\FLAG] rescues the cuticle hypopigmentation phenotype caused by expression of ATP7[Scer\UAS.T:Zzzz\FLAG] under the control of Scer\GAL4[pnr-MD237]. Co-expression of Scox[GD898] does not suppress the cuticle hypopigmentation phenotype caused by expression of ATP7[Scer\UAS.T:Zzzz\FLAG] under the control of Scer\GAL4[pnr-MD237]. Co-expression of ATP7[Scer\UAS.T:Zzzz\FLAG] suppresses the rough eye phenotype caused by expression of Ctr1B[Scer\UAS.T:Zzzz\FLAG] under the control of Scer\GAL4[GMR.PFa]. Co-expression of ATP7[Scer\UAS.T:Zzzz\FLAG] has no effect on the eye phenotype caused by expression of Ctr1A[GD16726] under the control of Scer\GAL4[GMR.PFa].
Expression of ATP7[Scer\UAS.T:Zzzz\FLAG] under the control of Scer\GAL4[pnr-MD237] in a Mvl[97f]/+ background does not significantly affect pigmentation or thoracic development compared to overexpression in a wildtype background. Simultaneous overexpression of ATP7[Scer\UAS.T:Zzzz\FLAG] and Mvl[Scer\UAS.T:Zzzz\FLAG] by Scer\GAL4[pnr-MD237] causes severe hypopigmentation and a further reduction in thorax width compared to overexpression of ATP7[Scer\UAS.T:Zzzz\FLAG] alone.
The loss of pigmentation seen in a stripe down the midline of the notum of ATP7[Scer\UAS.T:Zzzz\FLAG]; Scer\GAL4[pnr-MD237] adults is suppressed by Ctr1A[Scer\UAS.T:Zzzz\FLAG] but not by CCS[Scer\UAS.T:Zzzz\FLAG] or Atox1[Scer\UAS.T:Zzzz\FLAG].
