Tyrosine kinase receptor that, despite substitutions of key catalytic residues in the kinase domain, retains residual catalytic activity enabling autophosphorylation. ERBB3 functions primarily as a heterodimer, preferentially partnering with ERBB2/HER2, which phosphorylates ERBB3 on specific tyrosine residues and provides the kinase activity required for downstream signalling. ERBB3 binds neuregulins NRG1 and NRG2 through its extracellular domain, which induces conformational change from a tethered autoinhibited state to an extended conformation competent for dimerization.

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.
