CC -!- FUNCTION: Major sphingomyelin synthase at the Golgi apparatus (By
CC similarity). Catalyzes the reversible transfer of phosphocholine moiety
CC in sphingomyelin biosynthesis: in the forward reaction transfers
CC phosphocholine head group of phosphatidylcholine (PC) on to ceramide
CC (CER) to form ceramide phosphocholine (sphingomyelin, SM) and
CC diacylglycerol (DAG) as by-product, and in the reverse reaction
CC transfers phosphocholine from SM to DAG to form PC and CER. The
CC direction of the reaction depends on the levels of CER and DAG in Golgi
CC membranes (By similarity). Does not use free phosphorylcholine or CDP-
CC choline as donor. Regulates receptor-mediated signal transduction via
CC mitogenic DAG and proapoptotic CER, as well as via SM, a structural
CC component of membrane rafts that serve as platforms for signal
CC transduction and protein sorting (PubMed:22580896, PubMed:16879426) (By
CC similarity). Plays a role in secretory transport via regulation of DAG
CC pool at the Golgi apparatus and its downstream effects on PRKD1 (By
CC similarity). {ECO:0000250|UniProtKB:Q86VZ5,
CC ECO:0000269|PubMed:16879426, ECO:0000269|PubMed:22580896}.
CC -!- FUNCTION: (Microbial infection) Contributes to the brain SM production
CC for Japanese encephalitis virus attachment and infection.

CC -!- TISSUE SPECIFICITY: Isoform 1 is widely expressed, isoform 2 shows a
CC more narrow distribution and isoform 3 is detected only in testis and
CC heart. {ECO:0000269|PubMed:16226406}.
CC -!- INDUCTION: [Isoform 1]: Induced by TNF-alpha.
CC {ECO:0000269|PubMed:16226406}.
CC -!- INDUCTION: [Isoform 2]: Induced by TNF-alpha.
CC {ECO:0000269|PubMed:16226406}.
CC -!- DISRUPTION PHENOTYPE: Null mice have hearing impairments with stria
CC vascularis (SV) in these mice exhibiting atrophy and disorganized
CC marginal cells resulting in significantly smaller endocochlear
CC potentials (EPs). These decreased EPs, together with abnormal KCNQ1
CC expression patterns, increase with age. There is a decrease in plasma,
CC liver, and macrophage sphingomyelin (59%, 45%, and 54%, respectively)
CC and a dramatic increase in glycosphingolipids. No change in ceramide,
CC total cholesterol, phospholipids nor triglycerides levels. Diminished
CC macrophage MAP kinase and NFKB1 activation is observed. Atherosclerosis
CC in SMS1(-/-)/LDLR(-/-) mice is significantly decreased.
CC {ECO:0000269|PubMed:22580896, ECO:0000269|PubMed:22641779}.
CC -!- SIMILARITY: Belongs to the sphingomyelin synthase family.
