| Research Abstract |
Two sphingomyelin synthase, SMS1 and SMS2, are structurally homologous proteins but exhibit different cellular localization. In this study, mice deficient either for Sms1 or Sms2 gene were generated. Through the phenotypic analyses of Sms1KO and Sms2KO mice, the enzymes partially compensate in sphingomyelin biosynthesis but play different roles in biological aspects and physiology.
