UASt regulatory sequences drive expression of a 3.3kb Mmus\Numb cDNA. Xenopus β-globin 5' UTR sequences sequence encoding a Tag:MYC epitope are added at the N-terminal end of the cDNA sequence. The encoded protein is predicted to have an additional 44 amino acid residues, MEEKLISEEDLEDGTRVKLRNLSKVTQLVKGTAKIQSQVVKVN, at the N-terminal end.
Expression of Mmus\NumbScer\UAS.cZa in the SOP lineage, under the control of Scer\GAL4sca-537.4 causes balding of the notum due to transformation of IIA daughter into a second IIB and subsequent transformation of IIIb's sheath daughter into another neuron, resulting in mutant external sensory organs with as many as four neurons.
Scer\GAL4h-1J3/Mmus\NumbUAS.Tag:MYC is a suppressor of neuron phenotype of numb1
Scer\GAL4h-1J3 induced expression rescues the neuronal phenotype of numb1 embryos and rescues the two dorsal most es organs in abdominal hemisegments to wild type.
