Enables acylglycerol kinase activity; ceramide kinase activity; and diacylglycerol kinase activity. Acts upstream of or within ceramide biosynthetic process and lipid phosphorylation. Located in membrane. Is expressed in several structures, including alimentary system; integumental system; nervous system; respiratory system; and sensory organ. Human ortholog(s) of this gene implicated in Sengers syndrome and cataract 38. Orthologous to human AGK (acylglycerol kinase). [provided by Alliance of Genome Resources, Apr 2022]
