1.C.35.2.1









Cerebroside sulfate activator protein, CSAP or prosaposin (PSAP, GLBA, SAP1) of 524 aas. Saposin A, B, C and D are derived from prosaposin by proteolysis. Saposin-A and C stimulate the hydrolysis of glucosylceramide by beta-glucosylceramidase and galactosylceramide by beta-galactosylceramidase. Saposin-C apparently acts by combining with the enzyme and acidic lipids to form an activated complex, rather than by solubilizing the substrate. Saposin-B stimulates the hydrolysis of galacto-cerebroside sulfate by arylsulfatase A, GM1 gangliosides by β-galactosidase and globotriaosylceramide by α-galactosidase A. Saposin-B forms a solubilizing complex with the substrates of the sphingolipid hydrolases. Saposin-D is a specific sphingomyelin phosphodiesterase activator. Prosaposin behaves as a myelinotrophic and neurotrophic factor; these effects are mediated by its G-protein-coupled receptors, GPR37 and GPR37L1, undergoing ligand-mediated internalization followed by ERK phosphorylation signaling (Hiraiwa et al. 1999).

 Antimicrobial natural killer cell lysin, NK-lysin of 129 aas.  NK-lysin is involved in the inducible cytotoxicity of T and NK cells (Andersson et al. 1996). Recombinant NK-lysin inhibits hepatocellular carcinoma metastasis by downregulating FKBP3 and inhibiting oxidative phosphorylation and glycolysis (Fan et al. 2023).
