The von Hippel-Lindau tumor suppressor protein (VHL) recruits a Cullin 2 (Cul2) E3 ubiquitin ligase to downregulate HIF-1α, an essential transcription factor for the hypoxia response. Mutations in VHL lead to VHL disease and renal cell carcinomas. Inhibition of this pathway to upregulate erythropoietin production is a promising new therapy to treat ischemia and chronic anemia. Here we report the crystal structure of VHL bound to a Cul2 N-terminal domain, Elongin B (EloB), and Elongin C (EloC). Cul2 interacts with both the VHL BC box and cullin box and a novel EloC site. Comparison to other cullin E3 ligase structures shows that there is a conserved, yet flexible, cullin recognition module and that cullin selectivity is influenced by distinct electrostatic interactions. Our structure provides a structural basis for the study of the pathogenesis of VHL disease and the rationale design of novel compounds that may modulate cullin–substrate receptor interactions.
