Thus, the two substrates of this enzyme are CDP-choline and sphingosine, whereas its two products are CMP and sphingosyl-phosphocholine.

This enzyme belongs to the family of transferases, specifically those transferring non-standard substituted phosphate groups. The systematic name of this enzyme class is CDP-choline:sphingosine cholinephosphotransferase. Other names in common use include CDP-choline-sphingosine cholinephosphotransferase, phosphorylcholine-sphingosine transferase, cytidine diphosphocholine-sphingosine cholinephosphotransferase, and sphingosine choline phosphotransferase. This enzyme participates in sphingolipid metabolism.
