To verify these proteins, we carried out a co-IP that suggested T antigen might interact with ribosomal protein (RPL) 19, β-catenin, β-TRCP, p53, and CCAAT-enhancer-binding proteins (C/EBP) in lens tumor cells; the interactions were consistent with protein expression levels after T-antigen silencing. This evidence concerns the gene TP53 and neoplasm.
