NCIt definition : A small molecule inhibitor of Nedd8 activating enzyme (NAE) with potential antineoplastic
activity. Pevonedistat binds to and inhibits NAE, which may result in the inhibition
of tumor cell proliferation and survival. NAE activates Nedd8 (Neural precursor cell
expressed, developmentally down-regulated 8), an ubiquitin-like (UBL) protein that
modifies cellular targets in a pathway that is parallel to but distinct from the ubiquitin-proteasome
pathway (UPP). Functioning in diverse regulatory activities, proteins conjugated to
UBLs like Nedd8 typically are not targeted for proteasomal degradation.;
