ERBB3, also known as The Human Epidermal Growth Factor Receptor3 (HER3), constitutes a member of the receptor tyrosine kinase family, playing pivotal roles in the biological processes of both normal and tumor cells. The HER family receptors consist of extracellular ligand-binding domains, transmembrane domains, intracellular kinase domains, and C-terminal tails.
The ERBB3 gene is located on the long arm of human chromosome 12, encoding a 180 kDa protein. Its extracellular domain comprises four subdomains, with subdomains I and III responsible for ligand binding, while subdomains II and IV are rich in cysteine residues. HER3 exhibits widespread expression in various human tissues, including the gastrointestinal tract, urinary tract, respiratory tract, reproductive tract, skin, endocrine, and nervous system cells.
Fig.1 Structure and activation of HER receptors.1
ERBB3 stands as a unique member of the EGFR family, possessing little to no intrinsic intracellular tyrosine kinase activity. However, divergence exists among key residues in the kinase domain of ERBB3, leading to its adoption of a conformation resembling an inactive state. Activation of ERBB3 through neuregulin interactions initiates the PI3K/AKT and MAPK signaling pathways, fostering cellular proliferation.

ERBB3 is expressed in various cancers and is closely associated with tumorigenesis, tumor progression, and drug resistance. While ERBB3 alone may not initiate tumorigenesis, its dimerization with other EGFR family members (such as HER2) may contribute to tumor development. Furthermore, ERBB3 expression levels correlate with disease advancement and/or unfavorable prognoses across various cancer types, encompassing breast, colorectal, gastric, lung, skin, and pancreatic cancers.
