Receptor tyrosine-protein kinase erbB-2, also known as CD340 (cluster of differentiation 340), proto-oncogene Neu, Erbb2 (rodent), or ERBB2 (human) is a protein that in humans is encoded by the ERBB2 gene, which is also frequently called HER2 (from human epidermal growth factor receptor 2) or HER2/neu.
HER2 ("Neu, ErbB-2, CD340") — мембранный белок, тирозиновая протеинкиназа семейства рецептора эпидермального фактора роста "EGFR/ErbB", кодируемый геном человека "ERBB2".
