|Gene Description||ERBB3, erb-b2 receptor tyrosine kinase 3, encodes HER3, which is one of three ERBB members of the EGFR receptor tyrosine kinase family, which activates PI3K-AKT-mTOR and RAS-RAF-MEK-ERK pathways to promote cell survival and proliferation (PMID: 17471238). Activating Erbb3 mutations have been observed in a several tumor types, including lung and gastric and colon adenocarcinomas (PMID: 31519989) and Erbb3 mutations are also associated with acquired drug resistance (PMID: 31351986).|
