Figure 6From: Comparison of p53 and the PDZ domain containing protein MAGI-3 regulation by the E6 protein from high-risk human papillomavirusesComparison of E6-mediated ubiquitination of p53 and MAGI-3. Panel A. p53 ubiquitination in nuclear and cytoplasmic extracts from cells transfected with plasmids expressing pcDNA3 (control), MDM2 and HPV-16 E6 as indicated. Panel B. MAGI-3 ubiquitination from cells transfected with plasmids expressing pcDNA3 (control), HPV-16 E6, HA-tagged ubiquitin (Ub) alone, or HPV-16 E6 + HA-tagged ubiquitin (Ub). Panel C. MAGI-3 protein levels in cells transfected with plasmids expressing pcDNA3 (control), HPV-16 E6, HA-tagged ubiquitin (Ub) alone, or HPV-16 E6 + HA-tagged ubiquitin (Ub).Back to article page
