Human epidermal growth factor receptor 2 (HER-2)/epidermal growth factor receptor-2 (ErbB-2), is a key receptor linked to metastasis in tumours. The oncogenic ErbB-2 receptor has intrinsic receptor tyrosine kinase (RTK) activity. The receptor is activated by ligand binding which induces receptor dimerization. These RTK complexes can activate mitogen-activated protein kinase (MAPK) and phosphoinositol 3′-kinase (PI3K)/Akt pathways. This peptide has been identified as a substrate for HER-2/ErbB-2 as it is phosphorylated upon receptor activation and therefore acts as a marker for receptor activation in kinases assays.
