ERBB2, often known as HER-2/neu, a single-pass type I membrane protein, is a member of the epidermal growth factor (EGF) receptor family of receptor tyrosine kinases. It is part of several cell surface receptor complexes. ERBB2 has no ligand binding domain of its own, and needs a coreceptor for ligand binding. Allelic variations at amino acid positions 654 and 655 of isoform a (positions 624 and 625 of isoform b) have been reported, with the most common allele Ile654/Ile655. There are several transcript variants resulting from alternative splicing events. Some isoforms have not been fully characterized yet.

Amplification and/or overexpression of the ERBB2 gene has been reported in numerous cancers, including breast and ovarian tumors. Studies have suggested that ERBB2 overexpression represented a major negative prognostic indicator for patients with several human cancers, including endometrial carcinomas
Despite many promising new markers for ovarian cancer, CA125 remains the single best biomarker in the phase II and phase III specimens tested in this study.
