Claim: ERBB3 is a receptor tyrosine kinase located on the long arm of chromosome 12 and is encoded by 23,651 base pairs.
Evidence: Receptor tyrosine-protein kinase erbB-3, also known as HER3 (human epidermal growth factor receptor 3), is a membrane bound protein that in humans is encoded by the ERBB3 gene. The human ERBB3 gene is located on the long arm of chromosome 12 (12q13). It is encoded by 23,651 base pairs and translates into 1342 amino acids.
