To generate human ZBP1 (hZBP1)-expressing lentiviral vector, 3XFLAG epitope-tagged hZBP1 open reading was inserted into retroviral expression vector pQCXIH (Clontech). Murine ZBP1 (mZBP1) and mutants inserted in pQCXIH were described previously22 (link). All plasmids were verified by DNA sequencing. Retrovirus stock preparation and transduction were described previously14 (link). Reconstituted HT-29 or SVEC4-10 cell lines were selected in 500 or 400 μg/ml hygromycin, respectively.
