Measuring Diacylglycerol Kinase-θ Activity and Binding

B. Tu-Sekine, D. M. Raben

Research output: Chapter in Book/Report/Conference proceedingChapter


This section provides detailed protocols for the analysis of a mammalian diacylglycerol kinase, DGKθ, including an activity assay, a kinetic analysis, preparation of small unilamellar vesicles, and a vesicle pulldown assay. The goal of this section is to provide an overview of the unique challenges inherent in the study of an interfacial enzyme such as DGKθ and to outline methods useful for analysis. We include a short tutorial on selecting lipids for forming the interface since this is critical for a successful in vitro assay, and lipids are important regulators of this enzyme. The general principles can be applied to the study of other interfacial enzymes.
