Enables diacylglycerol kinase activity and phospholipid binding activity. Predicted to be involved in glycerolipid metabolic process; intracellular signal transduction; and lipid phosphorylation. Predicted to act upstream of or within lipid metabolic process and phosphorylation. Located in cytosol and plasma membrane. Is expressed in several structures, including alimentary system; cranial ganglion; integumental system; respiratory system; and sensory organ. Orthologous to human DGKA (diacylglycerol kinase alpha).
