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. | |||||||
ITB7_HUMAN | LIG_Talin | 770 | 779 | 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. | |||
Type: Binary Subtype: Pre‑translational | |||||||
Pre-translational mechanisms such as alternative splicing, alternative promoter-usage and/or RNA editing result in inclusion or removal of exons that contain an entire or partial motif. | |||||||
ITB1_HUMAN | LIG_Talin | 775 | 785 | 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). | |||
ITB1_HUMAN | LIG_Talin | 775 | 785 | 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). |
