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.

HIF1A_HUMAN | LIG_TAZ1 | 792 | 795 | Under normoxic conditions interaction of Hypoxia-inducible factor 1-alpha (HIF1A) with transcriptional coactivators such as CREB-binding protein (Crebbp) is inhibited by hydroxylation of N803. | 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_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 |
