ATM

Ataxia telangiectasia mutated. A checkpoint kinase which transduces genomic stress signals to stop cell cycle progression and promote DNA repair, acting via p53, a tumour suppressor protein. Its cognate gene, ATM (see below), is mutated in ataxia telangiectasia, a rare neurodegenerative disease characterised by ataxia telangiectasias, increased chromosome fragility when exposed to ionising radiation and predisposition to lymphomas.

ATM (Gene)
A gene on chromosome 11q22-q23, which encodes a PI3/PI4 cell-cycle checkpoint kinase that phosphorylates, thereby regulating a broad range of downstream proteins—e.g., tumor suppressor proteins p53 and BRCA1, checkpoint kinase CHK2, checkpoint proteins RAD17 and RAD9, and DNA repair protein NBS1.

Mutated in
Ataxia-telangiectasia.
