Function
- neurotrophic for midbrain dopaminergic neurons
- increases high-affinity dopamine uptake of dopaminergic neurons
- mediates activation of c-ret protein[2][3]
Structure
- secreted as disulfide-linked homodimer
- belongs to the TGF-beta family, GDNF subfamily
Compartment
Expression
- in the brain, predominantly expressed in the striatum
- isoform 2 is absent from most tissues except for low levels in intestine & kidney
- highest expression of isoform 3 is found in pancreatic islets
- isoform 5 is expressed at very low levels in putamen, nucleus accumbens, prefrontal cortex, amygdala, hypothalamus & intestine
- induced by cAMP, 12-O-tetradecanoylphorbol-13-acetate (TPA) & FGF2
Pathology
- mice defective in GDNF expression show renal agenesis & absence of enteric nervous system[4][5][6]
- isoform 3 is up-regulated in the middle temporal gyrus of patients with Alzheimer's disease
- isoform 2 shows no change
- defects in GDNF may be a cause of Hirschsprung disease type 3
- defects in GDNF are a cause of congenital central hypoventilation syndrome
