Reaction: ATM phosphorylates MDM2
- in pathway: Regulation of TP53 Degradation
ATM phosphorylates MDM2 on three serine residues (S386, S395, S407) and one threonine residue (T419) in vicinity to the RING domain. ATM-mediated phosphorylation of MDM2 in response to DNA damage (DNA double strand breaks) prevents MDM2 dimerization, binding of TP53 (p53) and MDM2-mediated ubiquitination of TP53 (Cheng et al. 2009, Cheng et al. 2011).
