LIG_PTB_Apo_2 - These phosphorylation-independent motifs bind to Dab-like PTB domains. Binding is not driven by contacts at the 0 or FY position, but instead is dependent upon the large number of hydrophobic and hydrogen bond contacts between motif and domain. |
A4_HUMAN | 756 | 763 | Binary | Physicochemical compatibility | 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). | details |
A4_HUMAN | 756 | 763 | Specificity | Altered binding specificity | 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). | details |
LIG_SH2_GRB2 - GRB2-like Src Homology 2 (SH2) domains binding motif. |
A4_HUMAN | 757 | 760 | Cumulative | Rheostatic | 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. | details |
