Anti-Her-2, clone YN00956m

HER2 (also known as HER2 / neu, C-erbB2, erbB2 or neu) is a transmembrane receptor tyrosine kinase, which is a carcinogenic gene. Its activation will cause malignant transformation and increase the malignant potential of cells (cell proliferation, invasion, etc.). HER-2 is over expressed in 15-25% of primary breast cancer. HER-2 can also be found in gastrointestinal cancer, gastroesophageal cancer, ovarian cancer, well differentiated endometrial cancer and some salivary duct tumors. HER2-expressed breast cancer is usually associated with estrogen and progesterone receptor negative. Therefore, the poor prognosis is related to the expression of HER2. Protein 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. [The UniProt Consortium]
