Her2
Her2, also known as Neu, ErbB-2, CD340 (cluster of differentiation 340) or p185, is a protein, that in humans, is encoded by the ERBB2 gene. Her2 is a member of the epidermal growth factor receptor (EGFR/ErbB) family. The kinase activity of ErbB2 can be activated without ligand if it is overexpressed and by association with other ErbB proteins. Overexpression of ErbB2 is detected in almost 40% of human breast cancers.
