UASt regulatory sequences drive expression of truncated Hsap\MAPT sequences corresponding to amino acid residues 45-441 of the '2N4R' isoform and tagged at the N-terminal with Tag:MYC.
Expression of Hsap\MAPT45-441.Scer\UAS.T:Hsap\MYC under the control of Scer\GAL4GMR.PU at 25[o]C results in an abnormal rough-eye phenotype. These eyes display fused and disordered ommatidia with irregular and missing bristles.
