Abstract
Protein neddylation is an evolutionarily conserved posttranslational modification that conjugates NEDD8 to its substrate, catalyzed by an E1-activating enzyme, E2-conjugating enzyme, and E3 ligase. Neddylation is essential for cellular homeostasis, and its dysregulation has been implicated in diverse human diseases, including cancer, neurodegenerative diseases, and metabolic disorders, making the process a promising therapeutic target. In this Review, we systematically summarize the biochemical activity and biological functions of neddylation; its alterations in human diseases, particularly in cancers; and its validation as an attractive target for cancer therapy. We provide an overview on the discovery of neddylation inhibitors and the progress of MLN4924 (pevonedistat) and TAS4464 clinical trials and critically evaluate the core challenges and emerging opportunities for therapeutic strategies targeting neddylation.

Usage information is collected from two different sources: this site (JCI) and Pubmed Central (PMC). JCI information (compiled daily) shows human readership based on methods we employ to screen out robotic usage. PMC information (aggregated monthly) is also similarly screened of robotic usage.
Various methods are used to distinguish robotic usage. For example, Google automatically scans articles to add to its search index and identifies itself as robotic; other services might not clearly identify themselves as robotic, or they are new or unknown as robotic. Because this activity can be misinterpreted as human readership, data may be re-processed periodically to reflect an improved understanding of robotic activity. Because of these factors, readers should consider usage information illustrative but subject to change.
