Von Hippel–Lindau tumor suppressor

（重定向自VHL）

The regulation of HIF1α by pVHL. Under normal oxygen levels, HIF1α binds pVHL through 2 hydroxylated proline residues and is polyubiquitinated by pVHL. This leads to its degradation via the proteasome. During hypoxia, the proline residues are not hydroxylated and pVHL cannot bind. HIF1α causes the transcription of genes that contain the hypoxia response element. In VHL disease, genetic mutations cause alterations to the pVHL protein, usually to the HIF1α binding site.

The von Hippel–Lindau tumor suppressor also known as pVHL is a protein that in humans is encoded by the VHL gene. Mutations of the VHL gene are associated with von Hippel–Lindau disease.
