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.
FAK1_HUMANLIG_SH2_IA389405Phosphorylation of Y397 in the SH2-binding motif of Focal adhesion kinase 1 (PTK2) induces binding to the Cytoplasmic protein NCK2 (NCK2) protein.

NTRK2_HUMANLIG_SH2_IA714730Phosphorylation of Y727 in the SH2-binding motif of BDNF/NT-3 growth factors receptor (NTRK2) induces binding to the Cytoplasmic protein NCK2 (NCK2) protein.

DAB1_MOUSELIG_SH2_IA212228Phosphorylation of Y220 in the SH2-binding motif of Disabled homolog 1 (Dab1) induces binding to the Cytoplasmic protein NCK2 (NCK2) protein.

DAB1_MOUSELIG_SH2_IA232235Phosphorylation of Y232 in the SH2-binding motif of Disabled homolog 1 (Dab1) induces binding to Cytoplasmic protein NCK2 (NCK2).

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.
DAB1_MOUSELIG_SH2_IA220223Alternative splicing removes the SH2-binding motif of Disabled homolog 1 (Dab1), abrogating binding to Cytoplasmic protein NCK2 (NCK2). NCK2-beta has a clear preference for splice variant 2 (with the YQYI motif) over splice variant 3 (with the YQTI motif). The authors theorise that since Adapter molecule crk (Crk) is directly linked to the C3G-Rap1 pathway, and NCK2-beta is linked to the Breast cancer anti-estrogen resistance protein 1 (Bcar1) (p130Cas) pathway, it is likely that isoforms 2 and 3 connect to different downstream cascades. It was suggested that the ability of different Dab1 isoforms to recruit distinct sets of SH2 domains implies a fine-tuning role of Dab1 splicing in the intricate series of events that underlie neuronal migration (Gao et al. (2012) (here)) (See also Katyal and Godbout (2004) (here) and Gao et al. (2010) (here)).

Type: Binary Subtype: Allostery
The binding properties of a motif or a motif-binding domain are modulated indirectly by allosteric effects resulting from PTM or effector binding at a site that is distinct from the actual interaction interface.
CD3E_HUMANLIG_SH3_5184188Ligand binding to the T cell receptor complex TCR-CD3 results in a conformational change that exposes an SH3-binding motif in T-cell surface glycoprotein CD3 epsilon chain (CD3E), resulting in recruitment of Cytoplasmic protein NCK2 (NCK2), involved in T cell activation.
