WebNeddylation of cullin proteins activates the SCF (Skp1-Cullin-F-box) E3 ubiquitin ligase complex by promoting complex formation and enhancing the recruitment of the E2-ubiquitin intermediate (10). While NEDD8 modification of VHL is not required for ubiquitination of HIF1-α, it is required for fibronectin matrix assembly (11). WebVHL binding requires specific recognition of hydroxylated Pro-564 of HIF-1 (28–30). The proline hydroxylation, cata-lyzed by a conserved family of prolyl-4-hydroxylases, relies on molecular oxygen and iron (31, 32), indicating these enzymes as oxygen sensors. Moreover, recent studies of HIF1 -VHL
