PSAP/Prosaposin Protein, Rat (HEK293, His)

PSAP, or Prosaposin, is predicted to possess several functions, including ganglioside binding activity, protein homodimerization activity, and scaffold protein binding activity. It is anticipated to be involved in processes such as ganglioside GM1 transport to the membrane, positive regulation of beta-galactosidase activity, and prostate gland development. Predicted to act upstream of or within processes with a negative effect on gene expression, it is also expected to be involved in animal organ development, glycosylceramide metabolic processes, and protein transport. PSAP is predicted to be located in the aggresome, extracellular region, and late endosome, with activity in the extracellular space and lysosome. The human ortholog(s) of this gene have been implicated in conditions such as atypical Gaucher's disease due to saposin C deficiency, combined saposin deficiency, and late-onset Parkinson's disease. PSAP exhibits biased expression in tissues such as the spleen, brain, and nine other tissues, indicating its involvement in diverse physiological processes.
