Enables kinase activity. Involved in ER to Golgi ceramide transport. Acts upstream of or within several processes, including ceramide metabolic process; lipid homeostasis; and mitochondrion morphogenesis. Located in cytosol and mitochondrion. Is expressed in several structures, including alimentary system; eye; nervous system; respiratory system; and urinary system. Human ortholog(s) of this gene implicated in autosomal dominant non-syndromic intellectual disability 34. Orthologous to human CERT1 (ceramide transporter 1).
