Human Alpha-Synuclein Protein, His Tag

  • Synonym
    SNCA,NACP,PARK1,alpha-Synuclein
  • Source
    Human Alpha-Synuclein, His Tag (ALN-H52H8) is expressed from E.coli cells. It contains AA Met 1 - Ala 140 (Accession # P37840-1).
    Predicted N-terminus: Met 1
  • Molecular Characterization
    Online(Met 1 - Ala 140) P37840-1

    This protein carries a polyhistidine tag at the C-terminus.

    The protein has a calculated MW of 16.3 kDa. The protein migrates as 19 kDa under reducing (R) condition (SDS-PAGE).

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >90% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in 100 mM NaAC, pH7.0. Normally trehalose is added as protectant before lyophilization.

  • Background
    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 Ca2+ 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.
