    SUBCELLULAR LOCALIZATION     intracellular
    basic FUNCTION
  • cell cycle G2 checkpoint control gene, required for S-phase and G2/M arrest in response to DNA damage or incomplete DNA replication
  • centrally involved in the activation of cell-cycle checkpoints by genotoxic agents or replication stress
  • phosphorylation-dependent function of RAD17 in an ATR-RAD17-Claspin-CHEK1-signaling cascade that responds to specific replication stress
  • similarly to other human genes involved in checkpoint mechanisms, plays a role in control of tumor growth
  • critical for the ATR-dependent activation of CHEK1 during checkpoint responses
  • exhibiting a distinctive pattern of upregulation followed by subsequent degradation after exposure to UV radiation in primary cells
  • its stabilization prevents the termination of checkpoint signalling, which in turn attenuates the cellular re-entry into cell-cycle progression
  • CELLULAR PROCESS cell cycle, checkpoint
    nucleotide, repair
    a component
  • RAD17/RAD3/RAD1, is the 9-1-1 complex
    small molecule
  • interacting with RAD1 (interaction protein-protein in the cell cycle checkpoint machinery)
  • MCM7, a core component of the DNA replication apparatus, is a novel RAD17-interacting protein
  • phosphorylated RAD17 interacts with Claspin and regulates its phosphorylation
  • plays a central role in establishment of the interaction between TOPBP1 and the RAD9A-HUS1-RAD1 complex at stalled replication forks
  • Claspin and RAD17 are reportedly involved in the DNA damage-induced phosphorylation of CHEK1, a hallmark of checkpoint activation
  • RAD9A is loaded by RAD17 onto damaged chromatin
  • USP20 is required for RAD17 protein stability in the steady-state and post DNA damage
  • gain of function mutant TP53 proteins cooperate with E2F4 to transcriptionally downregulate RAD17 and BRCA1 gene expression
  • cell & other
    Other phosphorylation by ATR is important for genomic stability and restraint of S phase but is not essential for cell survival
