motifs/domains
  • a Cyclin F-binding motif, in a region of RRM2 located between amino acids 40-65, containing two putative CY motifs
  • HOMOLOGY
    interspecies homolog to murine Rrm2
    Homologene

    text
  • is largely cytoplasmic
  • its expression is S phase-specific and required for DNA replication
  • basic FUNCTION
  • ribonucleoside diphosphate reductase activity
  • promoter responsible for cell-cycle specific expression
  • plays an active role in tumor progression
  • its activity is a prosurvival function inactivated by proteolysis during apoptosis
  • plays a significant role in the regulation of cell invasiveness, cell migration and tumor metastasis
  • CELLULAR PROCESS nucleotide, replication
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism purine/pyrimidine
    signaling
    pyrimidine biosynthetic pathway
    a component component of the ribonucleotide reductase
    INTERACTION
    DNA
    RNA
    small molecule metal binding,
    binding two iron ions
    protein
  • heterodimerizing with RRM1
  • positive role of RRM2 in tumor angiogenesis and growth through regulation of the expression of THBS1 and VEGFA
  • is a new interactor of the F-box protein CCNF
  • Cyclin F directly controls the ubiquitin-mediated degradation of RRM2
  • RRM2 regulates BCL2 protein stability, with RRM2 suppression leading to increased BCL2 degradation, and critical link between RRM2 and BCL2 in apoptosis signaling
  • E2F1 can promote colorectal cancer proliferation, migration, invasion and metastasis by regulating RRM2 transactivation
