General description
138 kDa calculated
The ErbB2 (HER2, c-Neu, ErbB2, c-erbB2, or HER2/neu) protein is member of the human epidermal growth factor receptor (HER) family. It is a receptor tyrosine kinase containing an intracellular kinase domain and an extracellular ligand domain, although no endogenous ligand has yet been found. ErbB2 dimerizes with ErbB1, 3, and 4, and can activate different pathways including the PI3K, PLCγ, and MAPK pathways, depending on the ErbB receptor involved. Coupling with ErbB3 activates the PI3K pathway, whereas coupling with any of these three receptors can induce the MAPK pathway. ErbB2 signaling promotes cell proliferation and inhibits apoptosis. ErbB2 is overexpressed in various cancers and may play a role in the development and metastasis of gliomas, and ovarian, breast, lung, and gastric cancer.
