| Post Translational Modification | Autophosphorylated. Autophosphorylation occurs in trans; i.e. one subunit of the dimeric receptor phosphorylates tyrosine residues on the other subunit (Probable). Ligand-binding increases phosphorylation on tyrosine residues (PubMed-27134172; PubMed-33497358). Signaling via SEMA4C promotes phosphorylation at Tyr-1248 (PubMed-17554007). Dephosphorylated by PTPN12 (PubMed-27134172). |
| Function | Protein tyrosine kinase that is part of several cell surface receptor complexes; but that apparently needs a coreceptor for ligand binding. Essential component of a neuregulin-receptor complex; although neuregulins do not interact with it alone. GP30 is a potential ligand for this receptor. Regulates outgrowth and stabilization of peripheral microtubules (MTs). Upon ERBB2 activation; the MEMO1-RHOA-DIAPH1 signaling pathway elicits the phosphorylation and thus the inhibition of GSK3B at cell membrane. This prevents the phosphorylation of APC and CLASP2; allowing its association with the cell membrane. In turn; membrane-bound APC allows the localization of MACF1 to the cell membrane; which is required for microtubule capture and stabilization. |
