靶點(diǎn)詳情

  • 功能：
    Involved in the ubiquitination and subsequent proteasomal degradation via the von Hippel-Lindau ubiquitination complex. Seems to act as a target recruitment subunit in the E3 ubiquitin ligase complex and recruits hydroxylated hypoxia-inducible factor (HIF) under normoxic conditions. Involved in transcriptional repression through interaction with HIF1A, HIF1AN and histone deacetylases. Ubiquitinates, in an oxygen-responsive manner, ADRB2.

    2. aldehyde dehydrogenase 2 (ALDH2) is found to be transcriptionally regulated by VHL and contributes to enhanced anthracyclines cytotoxicity in clear cell renal cell carcinoma cells. PMID: 28643803
    3. Study suggests that reduced expression of PBRM1 and VHL in clear cell renal cell carcinoma is correlated with an increased tumor aggressiveness. Low VHL expression identified as a risk factor for worse patient overall survival. PMID: 29169846
