Type: Binary Subtype: Physicochemical compatibility |
PTM of a residue in a motif or in its flanking regions alters the physicochemical and/or structural compatibility of the motif with its binding partner. This can either induce or enhance an interaction, or result in inhibition or even abrogation of an interaction.

P53_HUMAN | MOD_GSK3_1 | 30 | 37 | Phosphorylation of Cellular tumor antigen p53 (TP53) at S37 primes the protein for phosphorylation at S33 by Glycogen synthase kinase-3 beta (GSK3B). | details |
P53_HUMAN | DOC_WW_Pin1_4 | 30 | 35 | 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. | details |
P53_HUMAN | DOC_WW_Pin1_4 | 312 | 317 | 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. | details |
P53_HUMAN | DOC_WW_Pin1_4 | 78 | 83 | 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. | details |
P53_HUMAN | DEG_MDM2_1 | 19 | 26 | 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. | details |
Type: Binary Subtype: Pre‑translational |
Pre-translational mechanisms such as alternative splicing, alternative promoter-usage and/or RNA editing result in inclusion or removal of exons that contain an entire or partial motif.
|
P53_HUMAN | DEG_MDM2_1 | 19 | 26 | 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. | details |
P53_HUMAN | TRG_NES_CRM1_1 | 339 | 352 | 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. | details |
P53_HUMAN | DOC_USP7_1 | 359 | 363 | Alternative splicing removes the deubiquitinating enzyme USP7-binding motif of Cellular tumor antigen p53 (TP53), abrogating binding to Ubiquitin carboxyl-terminal hydrolase 7 (USP7). | details |
P53_HUMAN | DOC_USP7_1 | 364 | 368 | Alternative splicing removes the deubiquitinating enzyme USP7-binding motif of Cellular tumor antigen p53 (TP53), abrogating binding to Ubiquitin carboxyl-terminal hydrolase 7 (USP7). | details |
Type: Cumulative Subtype: Rheostatic |
Rheostatic switches gradually alter the affinity of a motif for a single binding partner by addition of multiple PTMs that additively contribute to this modulation. Additional modifications can either strengthen or weaken an interaction.

P53_HUMAN | LIG_PH_Tfb1 | 50 | 56 | 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). | details |
P53_HUMAN | LIG_TAZ2 | 19 | 25 | 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). | details |
