Background:

• Protein kinases are crucial therapeutic targets implicated in various human diseases.
• Developing robust and cost-effective assays is vital for kinase inhibitor discovery.
• High-throughput screening of chemical libraries is a standard initial step in drug discovery.

Purpose of the Study:

• To describe the purification of the protein kinase, eukaryotic elongation factor 2 kinase (eEF-2K).
• To detail the use of three biochemical assays for identifying small molecules targeting eEF-2K.
• To advance the initial hit identification phase in drug discovery for kinase inhibitors.

Main Methods:

• Purification of the eEF-2K protein kinase.
• Development and implementation of three distinct biochemical assay formats.
• High-throughput screening of chemical libraries against purified eEF-2K.

Main Results:
