Comments
  • FUNCTION: Non-amyloid component of senile plaques found in Alzheimer disease. Could act as a regulator of SNCA aggregation process. Protects neurons from staurosporine and 6 hydroxy dopamine (6OHDA)-stimulated caspase activation in a p53-dependent manner. Contributes to restore the SNCA anti-apoptotic function abolished by 6OHDA. Not found in the Lewy bodies associated with Parkinson disease.
  • SUBCELLULAR LOCATION: Cytoplasm.
  • TISSUE SPECIFICITY: Expressed predominantly in brain; concentrated in presynaptic nerve terminals.
  • PTM: Phosphorylated. Phosphorylation by G-protein coupled receptor kinases (GRK) is more efficient than phosphorylation by CK1, CK2 and CaM-kinase II.
  • DISEASE: Brain iron accumulation type 1 (NBIA1, also called Hallervorden-Spatz syndrome), a rare neuroaxonal dystrophy, is histologically characterized by axonal spheroids, iron deposition, Lewy body (LB)-like intraneuronal inclusions, glial inclusions and neurofibrillary tangles. SNCB is found in spheroids but not in inclusions.
  • SIMILARITY: Belongs to the synuclein family.
