  • Description

    Rabbit polyclonal to Alpha-synuclein (phospho S129)
  • Host species

  • Specificity

    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.
  • Tested applications

    Suitable for: WBmore details
  • Species reactivity

    Reacts with: Rat, Human
    Predicted to work with: Mouse, Cow, Dog, Non human primates
  • Immunogen

    Synthetic peptide corresponding to Rat Alpha-synuclein. Phosphopeptide corresponding to amino acid residues surrounding the phospho serine 129 of Rat alpha Synuclein.

  • Positive control

    • Rat cortex lysate.



Our Abpromise guarantee covers the use of ab42906 in the following tested applications.

  • Function

    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.
  • Tissue specificity

    Expressed principally in brain but is also expressed in low concentrations in all tissues examined except in liver. Concentrated in presynaptic nerve terminals.
  • Involvement in disease

    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.

  • Sequence similarities

    Belongs to the synuclein family.
  • Domain

    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.
  • Post-translational

    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.
