Recombinant full-length human MARK1 was expressed by baculovirus in Sf9 insect cells using an N-terminal GST tag. MARK1 is a member of the MARK family and is a serine/threonine-protein kinase that plays a key role in signal transduction. Due to its protein serine/threonine kinase activity, MARK1 is known to mediate phosphorylation of key proteins involved in signal transduction and cell communication. MARK1 phosphorylates microtubule-associated proteins and triggers microtubule disruption (1). Gene mutation studies performed in mice revealed that, after targeted disruption of the MARK1 gene, the mice lacked the ability to drink and displayed hind leg motor dysfunction (2).
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 chemical compounds have 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.
Kinase Enzyme System contains:
Kinase: MARK1, 10μg (Human, recombinant full-length). MW: ~125kDa. Substrate: Chktide (KKKVSRSGLYRSPSMPENLNRPR); derived from human CDC25C protein isoform A (amino acids 205–225). Other: Reaction Buffer, DTT.
Profile More Compounds In-House: ADP-Glo™ Kinase Assay + Kinase Enzyme System is optimized so that you are up and running in no time. Complete Systems: The Kinase Enzyme Systems include a recombinant kinase enzyme, a substrate appropriate for the enzyme, a reaction buffer, DTT and supplemental reagents as needed. Obtain Reliable Results: The broad dynamic range, the ease of use and better sensitivity obtained with ADP-Glo™ Kinase Assay result in less ambiguous data.
