CC   -!- FUNCTION: Non-amyloid component of senile plaques found in
CC       Alzheimer disease. Could act as a regulator of SNCA aggregation
CC       process. Protects neurons from staurosporine and 6-hydroxy
CC       dopamine (6OHDA)-stimulated caspase activation in a p53/TP53-
CC       dependent manner. Contributes to restore the SNCA anti-apoptotic
CC       function abolished by 6OHDA. Not found in the Lewy bodies
CC       associated with Parkinson disease.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm.
CC   -!- TISSUE SPECIFICITY: Expressed predominantly in brain; concentrated
CC       in presynaptic nerve terminals.
CC   -!- PTM: Phosphorylated. Phosphorylation by G-protein coupled receptor
CC       kinases (GRK) is more efficient than phosphorylation by CK1, CK2
CC       and CaM-kinase II.
CC   -!- SIMILARITY: Belongs to the synuclein family.
