A series of phospho specific antibodies to ATM protein kinase, the gene mutated in the hereditary disease ataxia-telangiectasia
Rockland Immunochemicals has developed a series of phospho specific antibodies to ATM protein kinase ATM, the gene mutated in the hereditary disease ataxia-telangiectasia, codes for a protein kinase that acts as a master regulator of cellular responses to DNA double-strand breaks
ATM is normally inactive and the question of how it is activated in the event of DNA damage (due to ionising radiation for instance) is central to understanding its function.
ATM protein is now shown to be present in undamaged cells as an inactive dimer.
Low doses of ionising radiation, which induce only a few DNA breaks, activate at least half of the total ATM protein present, possibly in response to changes in chromatin structure.
