ERBB3 encodes a member of the epidermal growth factor receptor (EGFR) family of receptor tyrosine kinases. This membrane-bound protein has a neuregulin binding domain but not an active kinase domain. It therefore can bind this ligand but not convey the signal into the cell through protein phosphorylation. However, it does form heterodimers with other EGF receptor family members which do have kinase activity. Heterodimerization leads to the activation of pathways which lead to cell proliferation or differentiation. Amplification of this gene and/or overexpression of its protein have been reported in numerous cancers, including prostate, bladder, and breast tumors. Alternate transcriptional splice variants encoding different isoforms have been characterized. One isoform lacks the intermembrane region and is secreted outside the cell. This form acts to modulate the activity of the membrane-bound form. Additional splice variants have also been reported, but they have not been thoroughly characterized.

Erb-b2 receptor tyrosine kinase 3 (ERBB3), also known as HER3, is an EGFR-family receptor that forms signalling heterodimers with other ERBB receptors. ABMIUM catalogue products linked below support research on ERBB3/HER3 biology.
Biological function: Erb-b2 receptor tyrosine kinase 3 (ERBB3/HER3) is an EGFR-family transmembrane receptor with impaired intrinsic kinase activity that signals through heterodimerisation with other ERBB receptors. Ligands including neuregulins promote receptor complex formation and downstream pathways such as PI3K-AKT, supporting cell growth, survival and differentiation.
