Type: Specificity Subtype: Competition | |||||||
Competitive binding of multiple binding partners to overlapping or adjacent, mutually exclusive interaction interfaces depends on local target protein abundance, which can be regulated by changing the expression level or subcellular localisation of the competitors, or by scaffolding. | |||||||
DAG1_HUMAN | LIG_WW_1 | 889 | 892 | The WW-binding motif for Dystrophin (DMD) and the SH3-binding motif for Growth factor receptor-bound protein 2 (GRB2) on Dystroglycan (DAG1) overlap, making their interactions mutually exclusive and competitive. | |||
DAG1_HUMAN | LIG_SH3_3 | 888 | 894 | The WW-binding motif for Dystrophin (DMD) and the SH3-binding motif for Growth factor receptor-bound protein 2 (GRB2) on Dystroglycan (DAG1) overlap, making their interactions mutually exclusive and competitive. | |||
DAG1_HUMAN | LIG_WW_1 | 889 | 892 | The WW-binding motif for Dystrophin (DMD) and the SH3-binding motif for Growth factor receptor-bound protein 2 (GRB2) on Dystroglycan (DAG1) overlap, making their interactions mutually exclusive and competitive. | |||
DAG1_HUMAN | LIG_SH3_3 | 888 | 894 | The WW-binding motif for Dystrophin (DMD) and the SH3-binding motif for Growth factor receptor-bound protein 2 (GRB2) on Dystroglycan (DAG1) overlap, making their interactions mutually exclusive and competitive. | |||
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. | |||||||
A9UF02_HUMAN | LIG_SH2_IC | 174 | 180 | Phosphorylation of Y177 in the SH2-binding motif of BCR/ABL fusion induces binding to the Growth factor receptor-bound protein 2 (GRB2) protein. | |||
EGFR_HUMAN | LIG_SH2_IC | 1092 | 1100 | Phosphorylation of Y1092 in the SH2-binding motif of Epidermal growth factor receptor (EGFR) induces binding to the Growth factor receptor-bound protein 2 (GRB2) protein. | |||
MET_HUMAN | LIG_SH2_IC | 1351 | 1360 | Phosphorylation of Y1356 in the SH2-binding motif of Hepatocyte growth factor receptor (MET) induces binding to the Growth factor receptor-bound protein 2 (GRB2) protein. | |||
SHC1_HUMAN | LIG_SH2_IC | 423 | 435 | Phosphorylation of Y427 in the SH2-binding motif of SHC-transforming protein 1 (SHC1) induces binding to the Growth factor receptor-bound protein 2 (GRB2) protein. | |||

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. | |||||||
A4_HUMAN | LIG_SH2_GRB2 | 757 | 760 | While phosphorylation of Y757 in the SH2-binding motif of Amyloid beta A4 protein (APP) induces binding to Growth factor receptor-bound protein 2 (GRB2), additional phosphorylation of T743 further increases the strength of the interaction. | |||
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. | |||||||
A4_HUMAN | LIG_SH2_GRB2 | 757 | 760 | 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). |
