UAS regulatory sequences drive expression of a truncated variant of stnB, lacking the MHD and the C-terminal tail (amino acids 1-903). The construct is tagged at the N-terminal end with Tag:polyHis and Tag:MYC.
Scer\GAL4elav.PU/stnBΔMHD.UAS.Tag:polyHis.Tag:MYC fails to rescue stnB12
Expression of stnBΔMHD.Scer\UAS.T:Zzzz\His6.T:Hsap\MYC under the control of Scer\GAL4elav.PU is unable to rescue the lethality associated with stnB12 mutant animals.
