Receptor tyrosine-protein kinase erbB-4 - ERBB4 - Homo sapiens | |||||||
| LIG_WW_1 | 1053 | 1056 | Specificity | Altered binding specificity | Phosphorylation-dependent binding of Receptor tyrosine-protein kinase erbB-4 (ERBB4) to the SH2 domains of Phosphatidylinositol 3-kinase regulatory subunit alpha (PIK3R1) results in signaling activation, while binding to the WW domains of E3 ubiquitin-protein ligase Itchy homolog (ITCH) to unphopshorylated ERBB4 results in ubiquitylation, endocytosis and ultimately degradation of ERBB4. | ||
| LIG_WW_1 | 1053 | 1056 | Binary | Pre‑translational | Alternative splicing removes the WW-binding motif of Receptor tyrosine-protein kinase erbB-4 (ERBB4), abrogating binding to E3 ubiquitin-protein ligase Itchy homolog (ITCH). The presence of a WW-binding motif mediates ERBB4 mono-ubiquitination and endocytosis by the WW domain-containing HECT-type E3 ubiquitin ligase ITCH. | ||

Tumor protein p73 - TP73 - Homo sapiens | |||||||
| LIG_WW_1 | 484 | 487 | Specificity | Competition | The transcriptional coactivator YAP1 and the ubiquitin ligase Itch competitively bind to the same WW-binding motif of p73. Binding of YAP1 prevents Itch-mediated ubiquitylation of p73, resulting in stabilisation, and increases trancriptional activity of p73. | ||
