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. | |||||||
| A4_HUMAN | LIG_PTB_Apo_2 | 756 | 763 | Phosphorylation of T743 adjacent to the PTB-binding motif of Amyloid beta A4 protein (APP) reduces the affinity for Amyloid beta A4 precursor protein-binding family B member 1 (APBB1). | |||
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. | |||||||
| ITB3_HUMAN | LIG_PTB_Apo_2 | 767 | 774 | Phosphorylation of Y773 in Integrin beta-3 (ITGB3) switches the specificity of ITGB3 from Talin-1 (TLN1) to Docking protein 1 (DOK1), with a 2-fold decrease of the affinity for TLN1 and close to a 400-fold increase of the affinity for DOK1. This switch results in negative regulation of integrin activation. | |||
| A4_HUMAN | LIG_PTB_Apo_2 | 756 | 763 | Phosphorylation of Y757 in APP (Amyloid beta A4 protein (APP)) switches its specificity from PTB domain containing proteins, like Amyloid beta A4 precursor protein-binding family B member 1 (APBB1), which is involved in trafficking and processing of APP, to SH2 domain containing proteins, such as Growth factor receptor-bound protein 2 (GRB2). | |||
| ITB3_HUMAN | LIG_PTB_Apo_2 | 779 | 786 | Phosphorylation of Integrin beta-3 (ITGB3) at Y785 switches the specificity of integrin from Kindlin-2 (Fermitin family homolog 2 (FERMT2)) to the adaptor protein SHC-transforming protein 1 (SHC1). | |||
