      Entrez Gene Number
      Entrez Gene SummaryThis gene encodes a member of the epidermal growth factor (EGF) receptor family of receptor tyrosine kinases. This protein has no ligand binding domain of its own and therefore cannot bind growth factors. However, it does bind tightly to other ligand-bound EGF receptor family members to form a heterodimer, stabilizing ligand binding and enhancing kinase-mediated activation of downstream signalling pathways, such as those involving mitogen-activated protein kinase and phosphatidylinositol-3 kinase. 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, shown here. Amplification and/or overexpression of this gene has been reported in numerous cancers, including breast and ovarian tumors. Alternative splicing results in several additional transcript variants, some encoding different isoforms and others that have not been fully characterized.

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: P04626 # Essential component of a neuregulin-receptor complex, although neuregulins do not interact with it alone. GP30 is a potential ligand for this receptor. Not activated by EGF, TGF- alpha and amphiregulin.
      SIZE: 1255 amino acids; 137910 Da
      SUBUNIT: Heterodimer with each of the other ERBB receptors (Potential). Interacts with PRKCABP and PLXNB1. Part of a complex with EGFR and either PIK3C2A or PIK3C2B. May interact with PIK3C2B when phosphorylated on Tyr-1196. Interacts with MEMO when phosphorylated on Tyr-1248.
      SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein.
      PTM: Ligand-binding increases phosphorylation on tyrosine residues (By similarity).
      SIMILARITY: SwissProt: P04626 ## Belongs to the protein kinase superfamily. Tyr protein kinase family. EGF receptor subfamily. & Contains 1 protein kinase domain.
