- Protein Name
- Receptor tyrosine-protein kinase erbB-3
- Gene Name
- ERBB3
- Organism
-
Homo sapiens
- Function
- Tyrosine-protein kinase that plays an essential role as cell surface receptor for neuregulins. Binds to neuregulin-1 (NRG1) and is activated by it; ligand-binding increases phosphorylation on tyrosine residues and promotes its association with the p85 subunit of phosphatidylinositol 3-kinase (PubMed:20682778). May also be activated by CSPG5 (PubMed:15358134).
