Enables diacylglycerol kinase activity. Involved in several processes, including glycerolipid metabolic process; lipid phosphorylation; and negative regulation of protein kinase C signaling. Predicted to be located in cytosol and membrane. Predicted to be active in plasma membrane. Is expressed in several structures, including alimentary system; cardiovascular system; central nervous system; integumental system; and sensory organ. Orthologous to human DGKG (diacylglycerol kinase gamma). [provided by Alliance of Genome Resources, Apr 2022]
