Species: Human Host Species: Sf9 Insect Cell MW: 67 kDa Genbank #: NM_007181 Tag(s): N-terminal GST tag, C-terminal His-Avi-Tag a.a: 1-346 Description:Human hematopoietic progenitor kinase 1 (HPK1) also known as mitogen activated protein kinase 1 (MAP4K1), GenBank Accession No. NM_007181, a.a. 1-346, with N-terminal GST tag and C-terminal His-Avi-Tag, MW = 67 kDa. HPK1 is expressed in Sf9 insect cells via a baculovirus expression system. UniProt Q92918 Synonym(s): HPK1 protein, hematopoietic progenitor kinase 1, mitogen activated protein kinase 1 MAP4K1, HPK1 protein, HPK Specific Activity: 115 pmol/min/μg Assay Conditions: Assay was done in Kinase buffer containing 1 mM DTT using MBP substrate (0.2 mg/ml) and 20 μM ATP. Reaction was done at 30oC for 50 min. Amount of ATP transferred was calculated using Kinase-Glo reagent (Promega) Formulation: 40 mM Tris-HCl, pH 8.0, 110 mM NaCl, 2.2 mM KCl, 0.04% Tween20, 20% glycerol, 140 mM Imidazole Format: Aqueous buffer solution Storage / Stability: At least 6 months at -80°C. Avoid freeze/thaw cycles. Storing diluted enzyme is not recommended, if necessary, use carrier protein (BSA 0.1 – 0.5%). Application(s): Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling. Reference(s): 1.Hu, M., et al., Genes Dev. 1996; 10: 2251-2264
