UASt regulatory sequences drive expression of a Mmus\Numbl cDNA. Xenopus β-globin 5' UTR sequences sequence encoding a Tag:MYC epitope are added at the N-terminal end of the cDNA sequence.
Mmus\NumblUAS.Tag:MYC/Scer\GAL4h-1J3 is a suppressor of neuron phenotype of numb1
Scer\GAL4h-1J3-mediated expression of Mmus\NumblScer\UAS.cZa rescues the neuronal loss phenotype of numb1 embryos.
