  • Sample type: Biological fluids (SALIVA)
    Sample species: Human
    Review: We have found in our study that the concentration of salivary alpha-synuclein oligomer was significantly decreased in ASD patients than in healthy subjects. Alpha-synuclein oligomer levels mean in the saliva of patients with ASD, was found to be 0.1359±.059 ng/ml than in that of healthy children where its levels mean was 0.336 ± 0.26 ng/ml (p<0.001).

  • 功能：
    Neuronal protein that plays several roles in synaptic activity such as regulation of synaptic vesicle trafficking and subsequent neurotransmitter release. Participates as a monomer in synaptic vesicle exocytosis by enhancing vesicle priming, fusion and dilation of exocytotic fusion pores. Mechanistically, acts by increasing local Ca(2+) release from microdomains which is essential for the enhancement of ATP-induced exocytosis. Acts also as a molecular chaperone in its multimeric membrane-bound state, assisting in the folding of synaptic fusion components called SNAREs (Soluble NSF Attachment Protein REceptors) at presynaptic plasma membrane in conjunction with cysteine string protein-alpha/DNAJC5. This chaperone activity is important to sustain normal SNARE-complex assembly during aging. Plays also a role in the regulation of the dopamine neurotransmission by associating with the dopamine transporter (DAT1) and thereby modulating its activity.
