{Reference Type}: Journal Article {Title}: N/C-degron pathways and inhibitor development for PROTAC applications. {Author}: Wu Z;Huang Y;Liu K;Min J; {Journal}: Biochim Biophys Acta Gene Regul Mech {Volume}: 1867 {Issue}: 1 {Year}: 2024 Mar 30 {Factor}: 6.304 {DOI}: 10.1016/j.bbagrm.2023.194952 {Abstract}: Ubiquitination is a fascinating post-translational modification that has received continuous attention since its discovery. In this review, we first provide a concise overview of the E3 ubiquitin ligases, delving into classification, characteristics and mechanisms of ubiquitination. We then specifically examine the ubiquitination pathways mediated by the N/C-degrons, discussing their unique features and substrate recognition mechanisms. Finally, we offer insights into the current state of development pertaining to inhibitors that target the N/C-degron pathways, as well as the promising advances in the field of PROTAC (PROteolysis TArgeting Chimeras). Overall, this review offers a comprehensive understanding of the rapidly-evolving field of ubiquitin biology.
