Figure Legend Snippet: TFAP2A is functionally associated with TP63-binding sites. ( A ) Effect on the IRF6 enhancer activity of the addition of exogenous TP63 in H1299 cells as measured by luciferase activity. All luciferase graphs represent the mean fold increase of at least three independent biological ± SEM; Student’s t -test * P < 0.05. ( B ) Luciferase assay measuring the effect of the addition of increasing amounts of TFAP2A on TP63-mediated activation of the IRF6 enhancer region in H1299 cells. ( C ) Western blot analysis of exogenous TP63 and TFAP2A expression in H1299 cells. ( D ) Luciferase assay measuring the effect of the addition of increasing amounts of TFAP2A on TP63-mediated activation of the PVRL1 enhancer region in H1299 cells. ( E ) Quantitative ChIP-PCR comparing TP63 and TFAP2A binding to IRF6, FGFR2, JAG2, PVRL1 and PDGFC associated binding sites, expressed as fold enrichment compared to a negative control region within the same ChIP. Data represent the mean of two independent biological replicates. ( F ) Western blot validation of TP63 and TFAP2A depletion in HFKs used in recruitment ChIPs. ( G ) Quantitative ChIP-PCR comparing TP63 and TFAP2A binding to IRF6, FGFR2, JAG2 and PVRL1 associated binding sites in HFKs depleted for TP63 or TFAP2A compared to scrambled control. Results calculated as fold enrichment compared to a negative control region within the same ChIP and normalized to scrambled control to compare between antibodies and experiments. Data represent the mean of two independent biological replicates. ( H ) Quantitative ChIP-PCR of second negative control binding site (BCL2 upstream) in HFKs depleted for TP63 or TFAP2A expressed as fold change compared to scrambled control. Data represent the mean of two independent biological replicates.

Graph represents the mean fold increase of at least three independent biological ± SEM; Student’s t -test * P < 0.05, ** P < 0.01.
