The exact role of the central acidic domain of Mdm2 in p53 degradation remains unclear. We therefore performed a systematic and comprehensive analysis of the acidic domain using a series of short deletions and found that only a minor part of the domain was indispensable for Mdm2-mediated p53 ubiquitylation. Moreover, we identified a short stretch of acidic amino acids required for p53 degradation but not ubiquitylation, indicating that, in addition to p53 ubiquitylation, the acidic domain might be involved in a critical post-ubiquitylation step in p53 degradation. Rather than representing a single functional domain, different parts of the acidic region perform separate functions in p53 degradation, suggesting that it might be possible to therapeutically target them independently.
