Inhibitors of pcna polyubiquitination

Webb22 okt. 2024 · Two E3 ubiquitin ligases, RNF8 and CRL4 (Cdt2), participate in the DNA damage-induced degradation of p12. We discuss how these E3 ligases integrate the formation of Pol δ3 and ubiquitinated PCNA... WebbUbiquitination is a post-translational modification, in which either a single ubiquitin molecule or ubiquitin chain is conjugated to target proteins, giving rise to mono- or polyubiquitination, respectively. Polyubiquitinated proteins are subjected to proteolysis by the proteasome.
