Abstract
Disclosed are novel proteins, referred to as truncated glial cell line-derived neurotrophic factor (truncated GDNF) proteins, that promote dopamine uptake by dopaminergic cells and promote the survival of nerve cells. Also disclosed are processes for obtaining the truncated GDNF proteins by recombinant genetic engineering techniques.
