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.

SPY2_HUMAN | LIG_TKB | 55 | 60 | Phosphorylation of Y55 in Protein sprouty homolog 2 (SPRY2) is necessary for binding to the TKB domain of E3 ubiquitin-protein ligase CBL (CBL). | 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.

SPY2_HUMAN | LIG_TKB | 55 | 60 | While phosphorylation of Y55 induces binding, additional phosphorylation of T56 in the TKB-binding motif of Protein sprouty homolog 2 (SPRY2) lowers its binding affinity for E3 ubiquitin-protein ligase CBL (CBL). | details |
