Expression vectors pLEX-ZNF750 (wildtype) and pLEX-C2H2 mutant ZNF750 (C2H2 mutant) were generously provided by Dr Paul A. Khavari (Stanford University School of Medicine). We also used another ZNF750 expression vector, SHC003-ZNF750 (which we reported previously3 (link)), in some of the experiments to confirm that the results were not affected by different vector systems (Supplementary Figure 6). The shRNA construct for p63 was made with PLKO.1 backbone (Sigma-Aldrich) using Age I and EcoR I sites (Supplementary Table S3). LAMC2 over-expression and shRNA vectors were described previously.24 Pooled siRNAs targeting human ZNF750 (M-014417-01) and TINCR (R-015725-00-0005) and scramble siRNA (D-001210-01) were purchased from Thermo Scientific (Rockford, IL, USA) (Supplementary Table S3).
