CLK1 Kinase Enzyme System
Convenient, Scalable Kinase Profiling
The Kinase Enzyme Systems include a recombinant kinase enzyme, a substrate appropriate for the enzyme, a reaction buffer and supplemental reagents as needed. The CLK1 Kinase Enzyme System contains:
- CLK1 Kinase, 10ug (Human, recombinant; amino acids 129–end). MW: ~66kDa.
- Native Swine Myelin Basic Protein (MBP) Substrate.
- Reaction Buffer, DTT.
Recombinant human CLK1 (129–end) was expressed by baculovirus in Sf9 insect cells using an N-terminal GST tag. CLK1, also known as STY, is a member of the CDC2-like (or LAMMER) family of dual specificity protein kinases. The phosphorylated serine/arginine-rich (SR) proteins are involved in the pre-mRNA processing and releasing through nucleus into nucleoplasm. CLK1, which could phosphorylate the specific SR proteins such as ASF/SF2, may directly regulate the activity and compartmentalization of SR splicing factors.
The CLK1 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.
