ProteinStartEndSwitch TypeSwitch SubtypeSwitch DescriptionInformation

DEG_MDM2_1 - Motif found in p53 family members which confers binding to the N-terminal domain of MDM2.
P53_HUMAN1926BinaryPhysicochemical compatibilityPhosphorylation of Cellular tumor antigen p53 (TP53) on T18 (in vitro by Casein kinase I subfamily, requiring prior phosphorylation of S15) inhibits its binding to E3 ubiquitin-protein ligase Mdm2 (MDM2). In vivo, T18 is phosphorylated in response to DNA damage.

P53_HUMAN1926BinaryPre‑translationalAlternative promoter usage and alternative splicing removes the E3 ubiquitin ligase MDM2-binding motif of Cellular tumor antigen p53 (TP53), abrogating binding to E3 ubiquitin-protein ligase Mdm2 (MDM2). The splice variant without this motif is resistant to MDM2-mediated degradation, leading to a longer half-life.
