Species: Mouse Host Species: E. coli MW: 42 kDa Genbank #: NM_0011949 Tag(s): N-terminal His-tag a.a: full length Description:Human/Mouse ERK2/MAPK2 (K52R) (GenBank Accession No. NM_0011949), full length with mutation on lysine52 to arginine and with an N-terminal His-tag, MW=42 kDa, expressed in E. coli . The K52R mutation prevents ATP binding, making the kinase inactive. Synonym(s): ERK2, MAPK1, mitogen-activated protein kinase 1, Extracellular Signal-Regulated Kinase 2, PRKM Specific Activity: inactive Formulation: 45 mM Tris-HCl, pH 8.0, 124 mM NaCl, 2.4 mM KCl, 125 mM imidazole, 3 mM DTT, 10% glycerol. Format: Aqueous buffer solution Storage / Stability:

>6 months at -80°C.

Application(s): Useful as a substrate for MEK1. Reference(s):
