Abstract
The von Hippel-Lindau (VHL) protein is a tumor suppressor. Mutations in the VHL protein can give rise to tumors of multiple organ systems, including the central nervous system, the endocrine system, and the kidney. The VHL protein functions as a subunit of a multiprotein ubiquitin ligase that negatively regulates expression of a large collection of hypoxia-inducible genes controlled by hypoxia-inducible transcription factors (HIFs). The VHL ubiquitin ligase prevents inappropriate expression of these hypoxia-inducible genes when cells are grown in a plentiful supply of oxygen by targeting HIFs for rapid ubiquitylation and degradation by the proteasome.
