LIG_SH2_IIA - | |||||||
ERBB4_HUMAN | 1056 | 1059 | Binary | Pre‑translational | Alternative splicing removes the SH2-binding motif of Receptor tyrosine-protein kinase erbB-4 (ERBB4), abrogating binding to Phosphatidylinositol 3-kinase regulatory subunit alpha (PIK3R1). The SH2-binding motif overlaps with a WW-binding motif. Binding of these motifs is regulated in a phosphorylation-dependent manner, ensuring ERBB4 is either endocytosed or stabilised. | ||

LIG_SH2_STAT5 - STAT5 Src Homology 2 (SH2) domain binding motif. | |||||||
ERBB4_HUMAN | 1056 | 1059 | 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. | ||
