ATM/ATR, members of the phosphatidyl inositol 3-kinase-like family of serine/threonine protein kinases (PIKKs), are widely known as being central players in the mitotic DNA damage response (DDR), mounting responses to DNA double-strand breaks (DSBs) and single-stranded DNA (ssDNA) respectively. Activation of ATM by ionizing radiation results in the activation of signal transduction pathways that induce cell cycle arrest at G1/S, S and G2/M. ATR is required for cell cycle arrest in response to DNA-damaging agents such as ultraviolet radiation that cause bulky lesions.

Upon activation, ATM/ATR phosphorylate numerous targets to stabilize stalled replication forks, repair damaged DNA, and inhibit cell cycle progression to ensure survival of the cell and safeguard integrity of the genome. ATM and ATR are central players in activating cell cycle checkpoints and function as an active barrier against genome instability and tumorigenesis in replicating cells.

  • HY-P10280
    ATR kinase substrate peptide
    		Inhibitor
    ATR kinase substrate peptide (compound 45) is a potent and selective inhibitor of ATR (Ataxia Telangiectasia and Rad3 related) protein kinase (Ki=6 nM). ATR kinase substrate peptide inhibits ATR activity by competing with ATR kinase ATP-binding sites to block ATR mediated signaling. ATR kinase substrate peptide can be used to study the role of ATR kinase in DNA damage response.
