WebThe VHL (608537) tumor suppressor is a component of an E3 ubiquitin ligase complex that ubiquitinates HIF1-alpha (HIF1A; 603348) for subsequent destruction by the 26S proteasome (see 602706). VHLL functions as a dominant-negative VHL to protect HIF1-alpha (Qi et al., 2004). WebThe substrate (transcription factor hypoxia-inducible factor 1α, HIF1-α) binds to the VHL protein or SOCS box–containing proteins. The VHL protein binds to the Skp1 homologue elongin C and a ubiquitin homologue elongin B. Cul2 and the Roc1/Rbx1 RING finger protein are associated with the complex (Jackson et al., 2000).
