Figure 1 Model of 53BP1 Action in Promoting p53 Activity
53BP1 acts in the nucleoplasm as a scaffold linking USP28 to p53. The USP28 deubiquitylase activity promotes the conversion of an inactive form of p53 into an active protein competent for DNA binding. Inducers of p53-dependent responses such as genotoxic insults or centrosome imbalance signal independently of 53BP1 action. Molecular Cell , 3-4DOI: ( /j.molcel ) Copyright © 2016 Elsevier Inc.
