Prosaposin is a highly conserved 66kD glycoprotein which contains separate domains in tandem for four saposins, A, B, C, and D. These saposins are involved in lysosomal hydrolysis of GM1 ganglioside, gluco- and galactocerebrosides, sulfatides, and sphingomyelin and other sphingolipids. It also exists as a secretory protein in body fluids. Deficiency of PSAP saposin-B, PSAP saposin-C and PSAP saposin-D region are the cause of a variant of metachromatic leukodystrophy, atypical Gaucher disease and Tay-Sachs disease respectively. Alternative splicing results in multiple transcript variants encoding different isoforms. The gene maps to 10q21-q22 region of human chromosome.

Suitable for use in Western Blot. Other applications not tested.

Optimal dilutions to be determined by the researcher.
