The Kinase Enzyme Systems include a recombinant kinase enzyme, a substrate appropriate for the enzyme, a reaction buffer and supplemental reagents as needed. The EIF2AK2 Kinase Enzyme System contains:
- EIF2AK2 Kinase, 10μg (Human, recombinant; amino acids 252–end). MW: ~64kDa.
- Native Swine Myelin Basic Protein (MBP) Substrate.
- Reaction Buffer, DTT.
Recombinant human EIF2AK2 (252–end) was expressed by baculovirus in Sf9 insect cells using an N-terminal GST tag. EIF2AK2 (also known as double-stranded RNA-activated protein kinase) is a protein kinase shown to be involved in HIV/gp120-associated neurodegeneration. EIF2AK2 acts as a critical mediator of gp120 neurotoxicity and is a substrate for a family of protein kinases that respond to various forms of environmental stress. Activation of EIF2AK2 leads to its autophosphorylation and then phosphorylation of its natural substrate, the alpha subunit of eukaryotic protein synthesis initiation factor-2. EIF2AK2 plays a critical role in mRNA translation, cell proliferation and apoptosis. A novel cross-talk event between the EIF2AKs and p53 has been shown that has implications in cell proliferation and tumorigenesis.
EIF2AK2 NCBI Database Entry.
The EIF2AK2 Kinase Enzyme System can be purchased with or without the ADP-Glo™ Kinase Assay reagents. Used together, the ADP-Glo™ Kinase Assay + Kinase Enzyme Systems provide a convenient method for profiling the effect of lead compounds on kinase activity. Assay advantages include broad dynamic range, ease of use and high sensitivity. Kinase Enzyme Systems are manufactured by SignalChem. Bulk quantities available upon request.
Use with ADP-Glo™ Kinase Assay
The ADP-Glo™ Kinase Assay is a luminescent kinase assay that measures ADP formed from a kinase reaction; ADP is converted into ATP, which is a substrate in a reaction catalyzed by Ultra-Glo™ Luciferase that produces light. The luminescent signal positively correlates with ADP amount and kinase activity. The assay is well suited for measuring the effects of chemical compounds on the activity of a broad range of purified kinases, making it ideal for both primary screening as well as kinase selectivity profiling. The ADP-Glo™ Kinase Assay can be used to monitor the activity of virtually any ADP-generating enzyme (e.g., kinase or ATPase) using up to 1mM ATP.
