UASt regulatory sequences drive expression of amino acid residues 672-1400 of scrib (the PDZ domains) which are tagged at the C-terminal end with Tag:MYC.
Scer\GAL4wor.PA/scribPDZ.UAS.Tag:MYC fails to rescue scrib1
Expression of scribPDZ.Scer\UAS.T:Hsap\MYC under the control of Scer\GAL4wor.PA fails to restore normal asymmetric divisions in homozygous scrib1 stage 15 neuroblasts.
