    motifs/domains
  • a 40AA F-box motif
  • a putative protein -protein interaction motif
  • a RRM2 binding domain
  • a cyclin box domain, but in contrast to most cyclins, it does not bind or activate any cyclin-dependent kinases (CDKs)
  • HOMOLOGY
    Homologene

    text
  • localizes to both the centrosomes and the nucleus
  • basic FUNCTION
  • plays a role in cell cycle regulation
  • CCNF(Cyclin F)-mediated degradation of CCP110 is potentially required for the fidelity of mitosis and genome integrity
  • controls centrosome duplication and prevents chromosome instability by promoting the degradation of CCP110
  • is a hub that coordinates and synchronizes centrosome duplication with DNA replication to ensure proper cell division
  • controls genome stability through ubiquitin-mediated proteolysis
  • plays an important role in checkpoint control following ionizing radiation
  • CCNF ubiquitin ligase complex prevents DNA re-replication by targeting CDC6 for proteasomal degradation late in the cell cycle
  • CELLULAR PROCESS cell cycle, checkpoint
    PHYSIOLOGICAL PROCESS
    text G2/mitotic specific checkpoint
    PATHWAY
    metabolism
    signaling
    a component forming SCF complex (Skp1-Cdc53/Cul1-Fbox)
    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • binding and activating cyclin dependent protein kinase
  • biinding to cyclin B
  • CCP110 is essential for centrosome duplication and is an interactor and substrate of CCNF
  • RRM2 is a new interactor of the F-box protein CCNF
  • directly controls the ubiquitin-mediated degradation of RRM2
  • interacts with MYBL2 via the cyclin box domain and this interaction is important to suppress CCNA-mediated phosphorylation of MYBL2, a key step in MYBL2 activation
  • CDC6 and CCNF interact through defined sequence motifs that promote CDC6 ubiquitylation and degradation
