Predicted to enable several functions, including diacylglycerol kinase activity; enzyme binding activity; and transmembrane receptor protein tyrosine kinase activator activity. Involved in regulation of synaptic vesicle endocytosis. Located in glutamatergic synapse and presynapse. Is active in postsynapse. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; respiratory system; and sensory organ. Orthologous to human DGKQ (diacylglycerol kinase theta). [provided by Alliance of Genome Resources, Apr 2022]
