ProteinMotifStartEndSwitch descriptionInformation

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.
ATX1_HUMANLIG_14-3-3_1772777Phosphorylation of S775 by RAC-alpha serine/threonine-protein kinase (AKT1) in the 14-3-3-binding motif of Ataxin-1 (ATXN1) induces binding to the 14-3-3 protein zeta/delta (YWHAZ) protein.

Type: Specificity Subtype: Altered binding specificity
The balance of the competition for overlapping or adjacent, mutually exclusive interaction interfaces is tipped in favor of one of the interactors by PTM-dependent modulation of the intrinsic affinity of a binding region. Multiple, successive PTMs allow sequential switching of different binding partners in an ordered manner by step-wise alteration of binding specificity.
ATX1_HUMANLIG_ULM_U2AF65_1770775Phosphorylation of S775 switches binding specificity of Ataxin-1 (ATXN1) from the splicing factor Splicing factor U2AF 65 kDa subunit (U2AF2) to 14-3-3 proteins (e.g. 14-3-3 protein zeta/delta (YWHAZ)). While association with the spliceosome protects ATXN1 from self-association, its phosphorylation-dependent recruitment to 14-3-3 proteins (e.g. YWHAZ) might result in aggregation.
