DEG_MDM2_1 - Motif found in p53 family members which confers binding to the N-terminal domain of MDM2. | |||||||
P53_HUMAN | 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. | ||
P53_HUMAN | 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. | ||
TRG_NES_CRM1_2 - | |||||||
MDM2_HUMAN | 190 | 202 | Binary | Pre‑translational | Alternative splicing removes the nuclear export signal (NES) of E3 ubiquitin-protein ligase Mdm2 (MDM2), abrogating binding to Exportin-1 (XPO1). | ||
TRG_NLS_MonoExtC_3 - Monopartite variant of the classical basically charged NLS. C-extended version. | |||||||
MDM2_HUMAN | 181 | 187 | Binary | Pre‑translational | Alternative splicing removes the nuclear localisation signal (NLS) of E3 ubiquitin-protein ligase Mdm2 (MDM2), abrogating binding to Importin subunit alpha-1 (KPNA1). The exclusion from the nucleus is not complete however, as another NLS (466-473) is speculated to target splice variants to the nucleus, however, to the annotator it seems more likely that splice variants can dimerise with full-length MDM2 and be simultaneously transported into nucleus. |
