UASt regulatory sequences drive expression of amino acids 1-104 of brk that are tagged at the C-terminal end with a nuclear localisation signal (Tag:NLS(SV40-largeT)) and two copies of Tag:HA.
Expression of brkNLS.Scer\UAS.T:Ivir\HA1,T:SV40\nls2 under the control of Scer\GAL4en-e16E has no effect on the size of the adult wing.
