Webbto stress when needed, p53 family members have to be kept in check. In unstressed cells, p53 activity is restrained via the RING-type ubiquitin ligases Mdm2, Pirh2 and COP1. When cells encounter genotoxic stress, p53 protein levels rapidly increase. This correlates with a decrease in Mdm2 catalyzed poly-ubiquitylation WebbPotential model for the proteasomal degradation of p53 facilitated by Mdm2, Pirh2 and COP1 based on the investigations in H1299 cells (43, 45).
