Diacylglycerol kinase modulates the levels of diacylglycerol and phosphatidic acid, two critical lipid second messengers, yet little is known about the effects of cellular stimulation on the kinetic behavior of this enzyme. We examined the effects of alpha-thrombin and activating phospholipids on the activity and substrate affinity of a soluble(More)
Diacylglycerol kinases (DGKs) catalyze the ATP-dependent phosphorylation of diacylglycerols to generate phosphatidic acid and have been investigated in prokaryotic and eukaryotic organisms. Recently, a protein that is significantly similar to human DGK-theta, DGKA, was identified in Dictyostelium discoideum. It has been shown to possess DGK activity when(More)
The Fanconi anemia group C gene (FAC) encodes a 63-kDa protein that plays a role in the growth and differentiation of hematopoietic progenitor cells and in cellular resistance to bifunctional cross-linking agents. The function of the gene product is unknown, as are the factors that govern expression of the gene itself. Seeking to associate a function of(More)
