β-Synuclein is a presynaptic protein that plays an important role in neuronal plasticity and synaptic vesicle regulation. The synuclein family includes three members: α, β and γ isoforms. The presynaptic proteins are detected in the neocortex, hippocampus, striatum, thalamus, and cerebellum regions1,2. β-Synuclein has been shown to act as a negative regulator of α-synuclein aggregation both in vivo and in vitro1,2. Structure wise, the protein contains a highly conserved N-terminal domain which includes a repetitive amino acid motif, and a more divergent and highly acidic stretch at the C-terminal domain2,3.
Studies have shown overexpressed mRNA levels of β-synuclein in Parkinson's disease suggesting that the protein has a valuable role in maintaining homeostasis in the disease pathology. In addition, studies have shown the action of β-synuclein as a neurodegeneration-inducing factor that can cause cell loss when expressed in rat brains1,2.
β-Synuclein is also implicated with dementia involving Lewy bodies. To date, two mutations in the protein, V70M and P123H, have been identified in the sporadic and familial disease3.
Species reactivity key:
Anti-Beta-Synuclein Antibody (#APZ-036) is a highly specific antibody directed against an epitope of the rat protein. The antibody can be used in western blot analysis. It has been designed to recognize β-synuclein from human, mouse, and rat samples. The antibody is specific for β-synuclein. It will not cross-react with α-synuclein.
