MGI Phenotype

FUNCTION: Sphingomyelin, a major component of cell and Golgi membranes, is made by the transfer of phosphocholine from phosphatidylcholine onto ceramide, with diacylglycerol as a side product. The protein encoded by this gene is an enzyme that catalyzes this reaction primarily at the cell membrane. The synthesis is reversible, and this enzyme can catalyze the reaction in either direction. The encoded protein is required for cell growth. [provided by RefSeq, Oct 2008]
PHENOTYPE: Mice homozygous for a knock-out allele exhibit increased ceramide levels; decreased sphingomyelin, sphingomyelin-1-phosphate, and diacylglycerol levels; and resistance to lysenin-mediated cytolysis. [provided by MGI curators]
