Aurora B Kinase Enzyme System

The Kinase Enzyme Systems include a recombinant kinase enzyme, a substrate appropriate for the enzyme, a reaction buffer and supplemental reagents as needed. The Aurora B Kinase Enzyme System contains:

• Aurora B, 10μg (Human, recombinant full-length). MW: ~68kDa.
• Native Swine Myelin Basic Protein (MBP) Substrate.
• Reaction Buffer, DTT.

Recombinant full-length human Aurora B was expressed by baculovirus in Sf9 cells using an N-terminal GST tag. Aurora B is a member of the Aurora kinase family that associates with microtubules during chromosome movement and segregation. Aurora B localizes to the microtubules near kinetochores, specifically to the specialized microtubules called K-fibers. Aurora B inhibits the microtubule depolymerizing activity of mitotic centromere-associated kinesin (MCAK) by phosphorylating MCAK on Ser92. This phosphorylation also regulates MCAK translocalization from kinetochores to the centromere. Aurora B has been identified as a target for the development of new anticancer agents since inhibition of AURORA B gives rise to the more pronounced antiproliferative phenotype.

Aurora B NCBI Database Entry

The Aurora B 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.
