Mutation in the promoter region of KHS1 is linked with lower risk of type 2 diabetes. It is also referred to as MAP4K5 (mitogen-activated protein kinase kinase kinase kinase 5)_x000D_ Physical form_x000D_ Supplied in 50 mM Tris-HCl, pH 7.5, with 150 mM NaCl, 0.2 5mM DTT, 0.1 mM EGTA, 0.1 mM EDTA, 0.1 mM PMSF, and 25% glycerol._x000D_ Legal Information_x000D_ PRECISIO is a registered trademark of Sigma-Aldrich Co.
