Summary: Enables identical protein binding activity; neutral sphingomyelin phosphodiesterase activity; and phospholipid binding activity. Involved in sphingomyelin metabolic process. Acts upstream of or within several processes, including bone development; enzyme-linked receptor protein signaling pathway; and sphingolipid metabolic process. Located in Golgi cis cisterna and plasma membrane. Is expressed in several structures, including alimentary system; limb; nervous system; sensory organ; and skeleton. Used to study hypopituitarism; osteogenesis imperfecta; osteogenesis imperfecta type 2; and osteogenesis imperfecta type 3. Orthologous to human SMPD3 (sphingomyelin phosphodiesterase 3).

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.
