    SUBCELLULAR LOCALIZATION     intracellular
    basic FUNCTION
  • would be involved in ubiquitin-dependent protein catabolism
  • deubiquitinating enzyme that binds to the von Hippel-Lindau tumor suppressor protein and also regulates thyroid hormone activation by deubiquitinating type 2 iodothyronine deiodinase (Allen 2007)
  • player in Slit-Robo signaling in cancer cell migration and required for Slit responsiveness in breast cancer cells (Yuasa-Kawada 2009)
  • required for Slit-induced Robo1 relocation to the plasma membrane (Yuasa-Kawada 2009)
  • role in vertebrate commissural axon guidance and in SLIT1 signaling (Yuasa-Kawada 2009)
  • required for SLIT1 responsiveness of commissural neurons (Yuasa-Kawada 2009)
  • USP33 and USP20 coordinate ADRB2 recycling and resensitization
  • is a deubiquitinase that has been associated with a variety of physiological events
  • USP33 potently and specifically deubiquitinates CCP110, but not other cyclin-F substrates
  • is a previously unknown tumor-suppressing gene for colorectal cancer (CRC) by mediating the inhibitory function of Slit-Robo signaling on CRC cell migration
    a component
    small molecule
  • interacting with VHL (target for ubiquitination and degradation by pVHL E3 ligase)
  • interacting with SELENBP1 (Jeong 2009)
  • interacts with ROBO1 and is required for Slit-induced ROBO1 redistribution to the plasma membrane without affecting the total ROBO1 protein level (Yuasa-Kawada 2009)
  • USP33 interacts with CCP110 and localizes to centrioles primarily in S and G2/M phases, the periods during which centrioles duplicate and elongate
  • HERC2, a HECT domain-containing E3 ligase, as being responsible for polyubiquitination of USP33
  • ubiquitination by the E3 ligase NEDD4 and deubiquitination by the deubiquitinases USP20 and USP33 have been shown to regulate the lysosomal trafficking and recycling of agonist-activated ADRB2
  • BTRC interacted with USP33 independently of the classic binding motif for BTRC, and mediated USP33 degradation via the ubiquitin proteasome pathway
