Recombinant Human Persephin (PSPN)
Persephin (PSPN) belongs to the GDNF ligand subfamily of the TGF-beta superfamily. The amino acid sequence of human PSPN is about 30% analogous to human GDNF. PSPN is synthesized throughout the nervous system and presumably originates from both astroglial cells and neurons. It promotes the survival and growth of mesencephalic dopaminergic and motor neurons. It also plays a role in kidney development by promoting ureteric bud branching. PSPN binds to a receptor complex consisting of Ret tyrosine kinase and GFR-alpha-4.
