Epidermal growth factor receptor - EGFR - Homo sapiens | |||||||
| LIG_PTB_Phospho_1 | 1104 | 1110 | Binary | Physicochemical compatibility | Phosphorylation of Y1110 in the PTB-binding motif of Epidermal growth factor receptor (EGFR) induces binding to the Docking protein 1 (DOK1) protein. | ||
Integrin beta-1 - ITGB1 - Homo sapiens | |||||||
| LIG_Talin | 775 | 785 | Binary | Pre‑translational | Alternative splicing alters the flanking regions of the PTB-binding motif of Isoform Beta-1D of Integrin beta-1 (ITGB1), inducing higher affinity binding to Talin-1 (TLN1). Alteration of residue 788 from G to Q and alteration of residue 786 from A to P increases the binding affinity from 491 micromolar in the canonical Isoform Beta-1A of Integrin beta-1 (ITGB1) to 95 micromolar in Isoform Beta-1D of Integrin beta-1 (ITGB1). | ||
| LIG_Talin | 775 | 785 | Binary | Pre‑translational | Alternative splicing alters the flanking regions of the PTB-binding motif of Isoform Beta-1D of Integrin beta-1 (ITGB1), inducing higher affinity binding to Talin-2 (TLN2). The alteration of residue 788 from G to Q and alteration of residue 786 from A to P increases the binding affinity from 652 micromolar in the canonical Isoform Beta-1A of Integrin beta-1 (ITGB1) to 36 micromolar in Isoform Beta-1D of Integrin beta-1 (ITGB1). | ||
Integrin beta-3 - ITGB3 - Homo sapiens | |||||||
| LIG_PTB_Phospho_1 | 767 | 773 | Binary | Physicochemical compatibility | Phosphorylation of Y773 in the PTB-binding motif of Integrin beta-3 (ITGB3) induces binding to the Docking protein 1 (DOK1) protein. | ||
| LIG_PTB_Apo_2 | 767 | 774 | Specificity | Altered binding specificity | 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. | ||
| LIG_PTB_Phospho_1 | 767 | 773 | Specificity | Altered binding specificity | 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. | ||
Integrin beta-7 - ITGB7 - Homo sapiens | |||||||
| LIG_Talin | 770 | 779 | Specificity | Competition | The integrin regulator Talin-1 (TLN1) and the actin-crosslinking Filamins Filamin-A (FLNA) use overlapping binding sites on the cytoplasmic tails of beta integrin subunits Integrin beta-7 (ITGB7), which makes their interaction with beta integrin mutually exclusive. | ||
Interleukin-4 receptor subunit alpha - IL4R - Homo sapiens | |||||||
| LIG_PTB_Phospho_1 | 491 | 497 | Binary | Physicochemical compatibility | Phosphorylation of Y497 in the PTB-binding motif of Interleukin-4 receptor subunit alpha (IL4R) induces binding to the Insulin receptor substrate 1 (IRS1) protein. | ||

Phosphatidylinositol 4-phosphate 5-kinase type-1 gamma - Pip5k1c - Mus musculus | |||||||
| LIG_PTB_Talin | 645 | 648 | Binary | Pre‑translational | Alternative splicing removes the PTB domain-binding motif of Phosphatidylinositol 4-phosphate 5-kinase type-1 gamma (Pip5k1c), abrogating binding to Talin-1 (Tln1). Integrin receptors, Tln1 and Isoform PIPKIgamma661 of Phosphatidylinositol 4-phosphate 5-kinase type-1 gamma (Pip5k1c) (PIPKIgamma661) are recruited to focal adhesions, inducing synthesis of PI(4,5)P2. The regulated and localised generation of PI(4,5)P2 facilitates the assembly and/or disassembly of focal adhesions. | ||

Phosphorylation of Y649 by Src kinase enhances the interaction, possibly indirectly by inhibiting S650 phosphorylation. | ||
