    Summary
    Enables ceramide phosphoethanolamine synthase activity and sphingomyelin synthase activity. Involved in sphingomyelin biosynthetic process. Acts upstream of or within ceramide biosynthetic process. Predicted to be located in Golgi trans cisterna. Predicted to be active in Golgi membrane; endoplasmic reticulum membrane; and plasma membrane. Is expressed in several structures, including alimentary system; central nervous system; ear; limb; and respiratory system. Orthologous to human SGMS1 (sphingomyelin synthase 1).

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
