Antigen description

The oncoprotein ErbB2/HER2 (human epidermal growth factor receptor 2), also known as Neu or CD340, is a 185 kDa transmembrane tyrosine kinase of cell surface growth factor receptor family. It is present in a wide variety cell types of normal human fetal and adult tissues and is frequently overexpressed in human carcinomas (e.g. in 20-30% cases of breast cancer cells). Activation of ErbB2 triggers intracellular signalling events, which are essential for cell growth and differentiation. In the last 20 years ErbB2 antigen has become very important marker and therapy target in patient care.
