WebJan 18, 2008 · Neddylation inhibits binding of Cand1 and thereby allows the association of substrate recognition adaptors. Second, cullin neddylation helps to recruit the ubiquitin E2 enzyme to the ligase. This occurs through the ability of Nedd8 to selectively bind to the ubiquitin-charged E2 ( Kawakami et al., 2001, Sakata et al., 2007 ). WebApr 11, 2016 · Abstract MLN4924 is a recently discovered small molecule inhibitor of NEDD8-Activating Enzyme (NAE). Because cullin RING ligase (CRL), the largest family of E3 ubiquitin ligase, requires cullin neddylation for its activity, MLN4924, therefore, acts as an indirect inhibitor of CRL by blocking cullin neddylation.
