The HER2/CD340 protein is a multifunctional tyrosine kinase that is a component of the neuregulin receptor complex and regulates microtubule dynamics. Activated HER2/CD340 triggers the MEMO1-RHOA-DIAPH1 pathway, inhibits GSK3B on the cell membrane and promotes the binding of APC and CLASP2, which is critical for microtubule stability. HER2/CD340 Protein, Mouse (HEK293, His) is the recombinant mouse-derived HER2/CD340 protein, expressed by HEK293 , with C-10*His labeled tag.
