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. | |||||||
| DAB1_MOUSE | LIG_SH2_IA | 185 | 188 | Phosphorylation of Y185 in the SH2-binding motif of Disabled homolog 1 (Dab1) induces binding to Neuronal proto-oncogene tyrosine-protein kinase Src (Src). | |||
| DAB1_MOUSE | LIG_SH2_SRC | 198 | 201 | Phosphorylation of Y198 in the SH2-binding motif of Disabled homolog 1 (Dab1) induces binding to Neuronal proto-oncogene tyrosine-protein kinase Src (Src). | |||
| FAK1_HUMAN | LIG_SH2_SRC | 397 | 400 | Phosphorylation of Y397 in the SH2-binding motif of Focal adhesion kinase 1 (PTK2) induces binding to Neuronal proto-oncogene tyrosine-protein kinase Src (Src). | |||
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_MOUSE | LIG_SH2_IA | 220 | 223 | Alternative 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)). | |||
| DAB1_MOUSE | LIG_SH2_IA | 220 | 223 | Alternative splicing removes the SH2-binding motif of Disabled homolog 1 (Dab1), abrogating binding to Adapter molecule crk (Crk). Both Adapter molecule crk (Crk) and Crk-like protein (Crkl) bind equally well to variants 2 and 3. 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.

| DAB1_MOUSE | LIG_SH2_IA | 185 | 188 | Alternative splicing removes the SH2-binding motif of Disabled homolog 1 (Dab1), abrogating binding to Neuronal proto-oncogene tyrosine-protein kinase Src (Src). Splice variants 2 and 3 (only containing one of the YQxI motifs, i.e. Y185 and Y198) exhibit decreased tyrosine phosphorylation, suggesting both motifs are required for full activation of Dab1. Dab1 is likely to recruit Neuronal proto-oncogene tyrosine-protein kinase Src (Src) via these two YQxI motifs, which subsequently phosphorylates adjacent YxVP motifs (here). This was also suggested for Phosphatidylinositol 3-kinase regulatory subunit alpha (Pik3r1) and Suppressor of cytokine signaling 2 (Socs2). Gao et al. (2012) (here) suggests that the ability of different Dab1 isoforms to recruit distinct sets of SH2 domains allows a fine-tuning role for Dab1 splicing in the intricate series of events that underlie neuronal migration (See also Katyal & Godbout (2004) (here) and Gao et al.
