UASt regulatory sequences drive expression of a full length Hsap\GPR37 cDNA.
50 day old flies expressing Hsap\GPR37Scer\UAS.cYa under the control of Scer\GAL4elav.PLu show a reduction in average climbing activity compared to 5 day old flies of the same genotype. 50 day old flies expressing Hsap\GPR37Scer\UAS.cYa under the control of Scer\GAL4elav.PLu show an approximately 80% reduction in the number of dopaminergic neurons in the dorsomedial clusters of the brain compared to 5 day old flies of the same genotype.
In 40 day old flies expressing Hsap\GPR37Scer\UAS.cYa under the control of Scer\GAL4Ddc.PL, the number of dopaminergic (DA) neurons in the dorsomedial (DM) cluster of the brain is reduced compared to controls. The degree of reduction in the number of DA neurons correlates with the expression level of Hsap\GPR37Scer\UAS.cYa. The number of DA neurons in the DM clusters of newly eclosed flies expressing Hsap\GPR37Scer\UAS.cYa under the control of Scer\GAL4Ddc.PL is similar to that of control flies. The number of DA neurons in the DM clusters is reduced in 40 day old flies expressing Hsap\GPR37Scer\UAS.cYa under the control of Scer\GAL4elav-C155. The overall morphology of the central brain is normal in these flies. Retinal architecture and photoreceptor neuron number is also normal. Flies expressing Hsap\GPR37Scer\UAS.cYa under the control of Scer\GAL4ey.PH or Scer\GAL4GMR.PF have normal eye morphology and eye structure. Expression of Hsap\GPR37Scer\UAS.cYa under the control of Scer\GAL4how-24B or Scer\GAL4dpp.blk1 does not result in a mutant phenotype. Newly eclosed flies expressing Hsap\GPR37Scer\UAS.cYa under the control of Scer\GAL4ap-md544 have body fluid leaking from two spots located in a bilaterally symmetric fashion on the dorsal thorax at the junction between the notum and scutellum. The fluids quickly solidify and form two dark patches adhering to the cuticle.

Co-expression of one of TrxTScer\UAS.cUa, Trx-2Scer\UAS.cUa, dhdScer\UAS.cUa or Hsap\PARK2Scer\UAS.cYa dramatically improves the average climbing activity of 50 day old flies expressing Hsap\GPR37Scer\UAS.cYa under the control of Scer\GAL4elav.PLu.
Co-expression of TrxTD26A.K57I.Scer\UAS or TrxTC35A.Scer\UAS improves the average climbing activity of 50 day old flies expressing Hsap\GPR37Scer\UAS.cYa under the control of Scer\GAL4elav.PLu.
Co-expression of one of TrxTScer\UAS.cUa, TrxTD26A.K57I.Scer\UAS, TrxTC35A.Scer\UAS, Trx-2Scer\UAS.cUa, dhdScer\UAS.cUa or Hsap\PARK2Scer\UAS.cYa significantly rescues the reduction in the number of dopaminergic neurons in the dorsomedial clusters of the brain seen in 50 day old flies expressing Hsap\GPR37Scer\UAS.cYa under the control of Scer\GAL4elav.PLu.
The reduction in climbing ability seen in 50 day old flies expressing Hsap\GPR37Scer\UAS.cYa under the control of Scer\GAL4elav.PLu is made more severe by the addition of dhdP8/+ or dhdJ5/+.
Coexpression of Hsap\PARK2Scer\UAS.cYa suppresses the thoracic degeneration phenotype (leaking body fluid on the dorsal thorax) seen in newly eclosed flies expressing Hsap\GPR37Scer\UAS.cYa under the control of Scer\GAL4ap-md544. Coexpression of Hsap\PARK2Scer\UAS.cYa suppresses the reduction in the number of DA neurons in the DM clusters that is seen in 40 day old flies expressing Hsap\GPR37Scer\UAS.cYa under the control of Scer\GAL4Ddc.PL. Coexpression of parkdsRNA.Scer\UAS results in a dosage-dependent acceleration of the DA neuron degeneration that is seen in flies expressing Hsap\GPR37Scer\UAS.cYa under the control of Scer\GAL4Ddc.PL; flies co-expressing Hsap\GPR37Scer\UAS.cYa and two copies of parkdsRNA.Scer\UAS show the degeneration phenotype at 14 days of age, whereas flies expressing Hsap\GPR37Scer\UAS.cYa alone or Hsap\GPR37Scer\UAS.cYa and one copy of parkdsRNA.Scer\UAS have a relatively normal number of DA neurons in the DM clusters. The severity of the DA neuron degeneration phenotype is also enhanced.
