WebOct 13, 2024 · Summary. Ataxia-telangiectasia is caused by an autosomal recessive gene mutation. Both genetic parents must pass the mutation to a child in order for the condition to develop. This gene normally works to keep damaged cells from dividing. With the mutation, damaged cells may continue to divide, raising the risk of cancer. WebAtaxia Telangiectasia Mutated protein kinase (ATM) has recently come to the fore as a regulatory protein fulfilling many roles in the fine balancing act of metabolic homeostasis.

One of these phosphorylation sites (mouse Ser(18) and human Ser(15)) is a substrate for the ataxia telangiectasia-mutated (ATM) and ATM-related (ATR) protein kinases. Studies of p53(S18A) mice (with a germ-line mutation that replaces Ser(18) with Ala) have indicated that ATM/ATR phosphorylation of p53 Ser(18) is ... WebMay 16, 2013 · Many independent laboratories have since demonstrated that in replicating cells, ataxia telangiectasia mutated (ATM) is predominantly a nuclear protein that is involved in the early recognition and response to double-stranded DNA breaks.
