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. | ||
DOC_USP7_1 - The USP7 NTD domain binding motif variant based on the MDM2 and P53 interactions. | |||||||
| P53_HUMAN | 359 | 363 | Binary | Pre‑translational | Alternative splicing removes the deubiquitinating enzyme USP7-binding motif of Cellular tumor antigen p53 (TP53), abrogating binding to Ubiquitin carboxyl-terminal hydrolase 7 (USP7). | ||
| P53_HUMAN | 364 | 368 | Binary | Pre‑translational | Alternative splicing removes the deubiquitinating enzyme USP7-binding motif of Cellular tumor antigen p53 (TP53), abrogating binding to Ubiquitin carboxyl-terminal hydrolase 7 (USP7). | ||
DOC_WW_Pin1_4 - The Class IV WW domain interaction motif is recognised primarily by the Pin1 phosphorylation-dependent prolyl isomerase. | |||||||
| P53_HUMAN | 30 | 35 | Binary | Physicochemical compatibility | Phosphorylation of S33 in the Pin1-binding motif of Cellular tumor antigen p53 (TP53) induces binding to the Peptidyl-prolyl cis-trans isomerase NIMA-interacting 1 (PIN1) protein. | ||
| P53_HUMAN | 312 | 317 | Binary | Physicochemical compatibility | Phosphorylation of S315 in the Pin1-binding motif of Cellular tumor antigen p53 (TP53) induces binding to the Peptidyl-prolyl cis-trans isomerase NIMA-interacting 1 (PIN1) protein. | ||
| P53_HUMAN | 78 | 83 | Binary | Physicochemical compatibility | Phosphorylation of T81 in the Pin1-binding motif of Cellular tumor antigen p53 (TP53) induces binding to the Peptidyl-prolyl cis-trans isomerase NIMA-interacting 1 (PIN1) protein. | ||
LIG_PH_Tfb1 - | |||||||
| P53_HUMAN | 50 | 56 | Cumulative | Rheostatic | Multisite phosphorylation of S46 and T55 in the PH-like binding motif of Cellular tumor antigen p53 (TP53) gradually enhances its affinity for General transcription factor IIH subunit 1 (GTF2H1), an interaction involved in activation of transcription initiation and elongation by Cellular tumor antigen p53 (TP53). | ||
LIG_TAZ2 - | |||||||
| P53_HUMAN | 19 | 25 | Cumulative | Rheostatic | Multisite phosphorylation of S15 and T18 and S20 and S33 and S37 and S46 in the TAD region of Cellular tumor antigen p53 (TP53) additively enhances its affinity for CREB-binding protein (CREBBP). | ||
MOD_GSK3_1 - GSK3 phosphorylation recognition site | |||||||
| P53_HUMAN | 30 | 37 | Binary | Physicochemical compatibility | Phosphorylation of Cellular tumor antigen p53 (TP53) at S37 primes the protein for phosphorylation at S33 by Glycogen synthase kinase-3 beta (GSK3B). | ||
TRG_NES_CRM1_1 - Some proteins re-exported from the nucleus contain a Leucine-rich nuclear export signal (NES) binding to the CRM1 exportin protein. | |||||||
| P53_HUMAN | 339 | 352 | Binary | Pre‑translational | Alternative splicing removes the nuclear export signal (NES) of Cellular tumor antigen p53 (TP53), abrogating binding to Exportin-1 (XPO1) and export from the nucleus. | ||
