Recombinant human MELK (1-340) was expressed by baculovirus in Sf9 insect cells using an N-terminal GST tag. MELK or maternal embryonic leucine zipper kinase is a member of the Snf1/AMPK kinase family. MELK is a key regulator of the proliferation of malignant brain tumors including their stem cells (1). MELK transcript abundance correlates with malignancy grade in human astrocytomas and represents a therapeutic target for the management of the most frequent brain tumors in adult and children. MELK also plays a role in mammary carcinogenesis through inhibition of the pro-apoptotic function of Bcl-GL (2). Therefore, the kinase activity of MELK could be a promising molecular target for development of therapy for patients with breast cancers. 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: MELK, 10ug (Human, recombinant; amino acids 1-340). MW: ~61kDa. Substrate: ZIPtide (KKLNRTLSFAEPG). Other: Reaction Buffer, DTT.
