This 14-mer prosaptide sequence is derived from the active neurotrophic region in the amino-terminal portion of the saposin C domain. Synthetic peptides derived from this region are biologically active and are named “prosaptides.” Prosaposin and prosaptides are active on a variety of neuronal cells, stimulating sulfatide synthesis and increasing sulfatide concentration in Schwann cells and oligodendrocytes. This indicates that prosaposin and prosaptides are trophic factors for myelin formation.
