Cellular tumor antigen p53 - TP53 - Homo sapiens | |||||||
| DEG_MDM2_1 | 19 | 26 | Binary | Physicochemical compatibility | Phosphorylation 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. | ||
| DEG_MDM2_1 | 19 | 26 | Binary | Pre‑translational | Alternative 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. | ||
