The Quaternary Structure of the Cul1-Rbx1-Skp1-F-boxSkp2 Complex
The upper panel shows the structure derived from a partial SCF complex (Zheng et al., 2002). The lower panel shows a model extending this structure to include the majority of the Skp2 protein (from a Skp1-Skp2 structure [Schulman et al., 2000]) and an E2 enzyme (from the structure of a related RING finger protein complexed to an E2 enzyme [Zheng et al., 2000]).
