Material Safety Data Sheet (MSDS)

Saposins are specific low-molecular mass non-enzymic proteins, they participate in the lysosomal degradation of sphingolipids, which takes place by the sequential action of specific hydrolases. Saposins are also involved in trafficking and loading of lipids onto Cluster of Differentiation 1 (CD1) receptor proteins. These CD1 receptor proteins play a vital role in the innate and adaptive immune system by presenting these lipid antigens to T-cell receptors on the surface of T cells, triggering immune responses.

Saposin A activates the hydrolysis of galactosylceramide by b-galactosidase to produce ceramide and galactose; Saposin A deficiency causes galactosylceramide lipidosis. Combined saposin deficiency (CSAPD) is due to absence of all saposins, leading to a fatal storage disorder with hepatosplenomegaly and severe neurological involvement. Krabbe disease, atypical, due to saposin A deficiency (AKRD) is a disorder of galactosylceramide metabolism. Clinical features include infant neurologic regression hyporeflexia, generalized brain atrophy, and diffuse white matter demyelination.
