    basic FUNCTION
  • 19/22S regulator of proteasome, ATPase subunit contributing to the E3 ubiquitin ligase function of the VHL protein
  • involved in the ATP-dependent degradation of ubiquitinated protein
  • involvement in the control of cell proliferationb (Pollice 2004)
  • multifunctional protein, component of the regulatory subunit of the proteasome, involved in different cellular processes (Pollice 2007)
  • involved in protection of the human oncosuppressor CDKN2A from proteasomal degradation (Pollice 2007)
  • adenosine triphosphatase of 19S regulatory particles of the 26S proteasome, and transcriptional coactivator of thyroid hormone receptor (Satoh 2009)
    • CELLULAR PROCESS nucleotide, transcription

    PATHWAY
    metabolism
    signaling
    a component
  • component 26S (prosome-macropain) of multicatalytic proteinase complex of proteasome
  • complexing with VHL and HIF1A
    • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • VHL, HIF1A
  • interacts with the human immunodeficiency virus tat transactivator
  • directly bound PSMC3IP through the N-terminal domain possessing the leucine zipper structure (Satoh 2009)
  • directly binds AR and might participate in AR-mediated transcriptional activation in cooperation with PSMC3IP (Satoh 2009)
  • interacting with CDKN2A (Pollice 2004))
