UASt regulatory sequences drive expression of the 23 C-terminal residues of Hsap\ITM2B (this is a normal product of wild-type Hsap\ITM2B processing). The protein is tagged at the N-terminal with the Tag:SS(nec) signal peptide and with a Tag:polyHis tag.
Expression of one or two copies of Hsap\ITM2B2-23.Scer\UAS.T:SS-nec,T:Zzzz\His6 in the eye, under the control of Scer\GAL4GMR.PF does not result in any toxic effects at 25[o]C.
