  • Interaction between the VHL tumor suppressor and hypoxia inducible factor, and assay methods relating thereto
    Publication number: 20050003452
    Abstract: The invention relates to the finding that the VHL tumour suppressor protein regulates hypoxia inducible factor ? subunits, by targeting HIF ? for destruction in normoxic, but not hypoxic cells. The invention provides assays for modulators of this interaction, and peptides based upon HIF ? subunit sequences which may modulate this interaction.
