PHYSICAL PROPERTIES
STRUCTURE
motifs/domains
  • proline rich protein particulary within its C-terminal half where one fourth of amino-acids are proline
  • secondary structure
  • FBXO7 FP domain adopts an alpha/beta-fold similar to that of the PSMF1 FP domain
  • mono polymer monomer
    HOMOLOGY

    intracellular,cytoplasm,cytosolic
    basic FUNCTION
  • control of proteasome function including that in ubiquitin-dependent pathway of protein degradation
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component
  • FP (FBXO7/PSMF1) domains found in the F-box protein FBXO7 and the proteasome inhibitor PSMF1 mediate the homodimerization and heterodimerization of FBXO7 and PSMF1
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • FBXO7 interacts with proteins that are not substrates of the ubiquitin proteasome system, such as CDK6 and PSMF1
