Bioactivity | Globotriaosylsphingosine (lyso-Gb3), triacylsphingosine globulin, is a glycosphingolipid biomarker. Alpha-galactosidase A deficiency causes Fabry disease, an X-linked lysosomal storage disorder. A characteristic feature of Fabry disease is the abnormal accumulation of Globotriaosylsphingosine in the urine of the organism. Globotriaosylsphingosine also inhibits KCa3.1 channel expression, resulting in reduced Ca2+ levels. Thus, Globotriaosylsphingosine inhibits the differentiation of myofibroblasts into myofibroblasts and inhibits collagen synthesis in fibroblasts. Globotriaosylsphingosine is useful in the study of ascending thoracic aortic aneurysms in Fabry disease[1][2]. |
