Claim: MAP3K3(Protein Coding gene) is a hormone  encoded by the MAP3K3 gene in Homo sapiens (Human) that produces 626-amino acid polypeptide and is closely related to MEKK2, tobacco NPK, and yeast STE11. .
Evidence: Mitogen-activated protein kinase kinase kinase 3 is an enzyme that in humans is encoded by the MAP3K3 gene, which is located on the long arm of chromosome 17 (17q23.3).
