Saposin B is a small (79 amino acids), non-enzymatic glycosphingolipid activator protein required for the breakdown of cerebroside sulfates (sulfatides) in lysosomes. The protein can extract target lipids from membranes, forming soluble protein-lipid complexes that are recognized by arylsulfatase A.

Recombinant human saposin B is produced in E. coli as an N-terminal His-tag fusion and purified by proprietary chromatography techniques with subsequent removal of the tag through a site-specific proteolytic cleavage. Saposins are glycosylated in a native state; however, non-glycosylated recombinant saposins produced in E. coli retain their respective activation effects in functional in vitro assays.
