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. {PubMed:10358079, PubMed:15380516, PubMed:21555369}.

Target Background

The Her2/Neu (c-erB-2) proto-oncogene product is a trans-membrane receptor tyrosine kinase that is clinically indicated in a number of carcinomas. Overexpression of the Her2/Neu protein has been associated with ductal breast cancer as well as with pulmonary and gastric adenocarcinomas. A correlation between Her2/Neu and p53 has also been reported as overexpression of both proteins has been associated with early invasion and metastasis in bladder cancer.
