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 (By similarity).Summary:This gene encodes a member of the epidermal growth factor(EGF) receptor family of receptor tyrosine kinases. This proteinhas no ligand binding domain of its own and therefore cannot bindgrowth factors. However, it does bind tightly to other ligand-boundEGF receptor family members to form a heterodimer, stabilizingligand binding and enhancing kinase-mediated activation ofdownstream signalling pathways, such as those involvingmitogen-activated protein kinase and phosphatidylinositol-3 kinase.Allelic variations at amino acid positions 654 and 655 of isoform a(positions 624 and 625 of isoform b) have been reported, with themost common allele, Ile654/Ile655, shown here. Amplification and/oroverexpression of this gene has been reported in numerous cancers,including breast and ovarian tumors. Alternative splicing resultsin several additional transcript variants, some encoding differentisoforms and others that have not been fully characterized.
