Summary: Enables sphingomyelin phosphodiesterase activity. Involved in several processes, including fatty acid homeostasis; positive regulation of intestinal cholesterol absorption; and regulation of membrane lipid metabolic process. Predicted to be located in Golgi apparatus and microvillus. Predicted to be integral component of plasma membrane. Orthologous to human ENPP7 (ectonucleotide pyrophosphatase/phosphodiesterase 7).

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.
