Anti-Phospho-α-Synuclein: Rabbit alpha-Synuclein, Phospho-Ser129 Antibody

BACKGROUND Synucleins are small, soluble proteins expressed primarily in neural tissue and in certain tumors. The family includes three known proteins: alpha-Synuclein, beta-Synuclein, and gamma-Synuclein.1 All Synucleins have in common a highly conserved alpha-helical lipid-binding motif with similarity to the class-A2 lipid-binding domains of the exchangeable apolipoproteins. Synuclein family members are not found outside vertebrates, although they have some conserved structural similarity with plant ‘late-embryo-abundant proteins. The alpha- and beta-Synuclein proteins are found primarily in brain tissue, where they are seen mainly in presynaptic terminals. The gamma-Synuclein protein is found primarily in the peripheral nervous system and retina, but its expression in breast tumors is a marker for tumor progression.2 Normal cellular functions have not been determined for any of the Synuclein proteins, although some data suggest a role in the regulation of membrane stability and/or turnover.3 Mutations in alpha-Synuclein are associated with rare familial cases of early-onset Parkinson’s disease, and the protein accumulates abnormally in Parkinson’s disease, Alzheimer’s disease, and several other neurodegenerative illnesses.4 Phosphorylation of alpha-Synuclein at Ser 129 promoted fibril formation in vitro and these results highlight the importance of phosphorylation of filamentous proteins in the pathogenesis of neurodegenerative disorders.5
