Superfamily: Cullin, PONY binding domain

This superfamily includes the conserved C-terminal domain, termed the PONY-domain "Potentiation of Neddylation". This domain binds to cullins and to Rbx-1, components of an E3 ubiquitin ligase complex for neddylation. Neddylation is the process by which the C-terminal glycine of the ubiquitin-like protein Nedd8 is covalently linked to lysine residues in a protein through an isopeptide bond. The structure of this domain is composed entirely of alpha helices.
