  • 描述
    兔多克隆抗体to Alpha-synuclein (phospho S129)
  • 宿主
  • 特异性
    This antibody is specific for the 15 kDa alpha Synuclein protein phosphorylated at serine 129. Immunolabelling is blocked by the phosphopeptide used as an antigen but not by the corresponding dephosphopeptide.

WB 1/1000. Predicted molecular weight: 15 kDa.


  • 功能
    May be involved in the regulation of dopamine release and transport. Induces fibrillization of microtubule-associated protein tau. Reduces neuronal responsiveness to various apoptotic stimuli, leading to a decreased caspase-3 activation.
  • 组织特异性
    Expressed principally in brain but is also expressed in low concentrations in all tissues examined except in liver. Concentrated in presynaptic nerve terminals.
  • 疾病相关
    Genetic alterations of SNCA resulting in aberrant polymerization into fibrils, are associated with several neurodegenerative diseases (synucleinopathies). SNCA fibrillar aggregates represent the major non A-beta component of Alzheimer disease amyloid plaque, and a major component of Lewy body inclusions. They are also found within Lewy body (LB)-like intraneuronal inclusions, glial inclusions and axonal spheroids in neurodegeneration with brain iron accumulation type 1.
    Parkinson disease 1
    Parkinson disease 4
    Dementia Lewy body
  • 序列相似性
    Belongs to the synuclein family.
  • 结构域
    The 'non A-beta component of Alzheimer disease amyloid plaque' domain (NAC domain) is involved in fibrils formation. The middle hydrophobic region forms the core of the filaments. The C-terminus may regulate aggregation and determine the diameter of the filaments.
  • 翻译后修饰
    Phosphorylated, predominantly on serine residues. Phosphorylation by CK1 appears to occur on residues distinct from the residue phosphorylated by other kinases. Phosphorylation of Ser-129 is selective and extensive in synucleinopathy lesions. In vitro, phosphorylation at Ser-129 promoted insoluble fibril formation. Phosphorylated on Tyr-125 by a PTK2B-dependent pathway upon osmotic stress.
    Hallmark lesions of neurodegenerative synucleinopathies contain alpha-synuclein that is modified by nitration of tyrosine residues and possibly by dityrosine cross-linking to generated stable oligomers.
    Ubiquitinated. The predominant conjugate is the diubiquitinated form.
    Acetylation at Met-1 seems to be important for proper folding and native oligomeric structure.
