Type: Avidity‑sensing Subtype: |
Multiple low-affinity interactions give rise to high-avidity interactions that have increased binding strength, with more than additive affinity.

MDM4_HUMAN | LIG_14-3-3_1 | 364 | 369 | Optimal binding of 14-3-3 dimer to Hdmx in response to DNA damage requires phosphorylation of two 14-3-3-binding motifs by Chk2 kinase. Binding of 14-3-3 dimer is involved in inactivation of Hdmx, a negative regulator of p53, in response to DNA damage. | details |
MDM4_HUMAN | LIG_14-3-3_3 | 339 | 344 | Optimal binding of 14-3-3 dimer to Hdmx in response to DNA damage requires phosphorylation of two 14-3-3-binding motifs by Chk2 kinase. Binding of 14-3-3 dimer is involved in inactivation of Hdmx, a negative regulator of p53, in response to DNA damage. | details |
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.

MDM4_HUMAN | DOC_USP7_1 | 398 | 402 | Phosphorylation of S403 adjacent to the USP7-binding motif of Protein Mdm4 (MDM4) by Serine-protein kinase ATM (ATM) inhibits binding to the Ubiquitin carboxyl-terminal hydrolase 7 (USP7), thereby reducing deubiquitylation of Protein Mdm4 (MDM4). As a result, ubiquitylation by E3 ubiquitin-protein ligase Mdm2 (MDM2) is not countered and Protein Mdm4 (MDM4) is targeted for proteasomal degradation. | details |
