Description

Background

The ErbB family consists of four separate plasma membrane-binding receptor tyrosine kinases. One of them is erbB-2, and the other members are erbB-1, erbB-3 (neuregulin-binding; Lack of kinase domains) and erbB-4. The receptor tyrosine-protein kinase erbB-2 is a protein normally found on cell membranes and is encoded by the ERBB2 gene. The human protein is also often referred to as HER 2 (Human epidermal growth factor receptor 2) or CD340 (differentiated cluster 340). HER2 has binding activity with Hsp90 protein, protein tyrosine kinase and ubiquitination protein. ErbB2 regulates differentiation and apoptosis of neural stem cells in the cochlear nucleus through PI3K/Akt pathway. HER2 is an oncogenic factor that is overexpressed in bladder cancer and activates the oncogenic signaling pathway, thereby promoting tumor cell survival/proliferation[1][2][3][4].
