Catalyzes the biosynthesis of ceramide phosphoethanolamine (CPE) through the transfer of a phosphatidyl head group from cytidine 5'-diphosphate (CDP)-ethanolamine on to the primary hydroxyl of ceramide. an N-acylsphing-4-enine + CDP-ethanolamine = an N-acylsphing-4-enine 1-phosphoethanolamine + CMP + H(+) The majority of protein localizes to the Golgi apparatus. Belongs to the CDP-alcohol phosphatidyltransferase class-I family.
