Anti-phospho-alpha-Synuclein (Ser129)

alpha-Synuclein is a 140-amino acid intracellular protein encoded by the SNCA gene in humans. It is primarily localized to the synaptic terminal of neurons in both the central and peripheral nervous systems where it has a role in regulation of synaptic vesicle docking and neurotransmitter release. alpha-Synuclein is an intrinsically disordered, multi-domain protein. It exists as monomer in the cytoplasm, however, mutations, posttranslational modifications, and changes in cellular environmental conditions can induce oligomerization and aggregate formation that lead to various pathologies, including Parkinson's disease, Lewy body disease, multiple system atrophy (MSA), and amyotrophic lateral sclerosis (ALS). Phosphorylation of alpha-synuclein at serine 129 (Ser129) is increased in response to mitochondrial stress and is reduced by lysosome inhibition in SH-SY5Y cells. It enhances alpha-synuclein-induced neurotoxicity in Drosophila and rat models of Parkinson's disease. Levels of phosphorylated Ser129 (phospho-Ser129) are increased in Lewy bodies in postmortem brains from patients with Parkinson's disease and Lewy body disease compared with control individuals. Cayman's alpha-Synuclein (Phospho-Ser129) Polyclonal Antibody can be used for immunohistochemistry (IHC) and Western blot (WB) applications. The antibody recognizes alpha-synuclein (phospho-Ser129) at approximately 15 kDa from human, mouse, and rat samples.Synonyms: SNCA, alpha-Syn. Immunogen: Phosphopeptide corresponding to amino acid residues surrounding phospho-Ser129 of rat alpha-synuclein. MW: ~15 kDa.
