Synuclein is a small, soluble protein primarily expressed in neural tissue. The synuclein family includes three known proteins: alpha-synuclein, beta-synuclein, and gamma-synuclein. alpha-Synuclein is a very conserved, small acidic protein (140 residues) with a molecular weight of approximately 19kD that accounts for about 1% of total protein in neurons. It is concentrated primarily in presynaptic axon terminals and plays a central role in initiating Parkinson's disease. It is the principal constituent of Lewy bodies which are formed by protein aggregation and inclusion body formation. alpha-Synuclein lacks secondary or tertiary structure, so it belongs to the family of natively unfolded proteins, many of which act as chaperones. Much of this alpha-synuclein has been post-translationally modified to increase the rate of oligomerization. Mutant forms of alpha-Synuclein are associated with autosomal dominant Parkinson's disease. The mutations increase the aggregation rate of the resultant alpha-synuclein beta-Synuclein is found primarily in brain tissue and is seen mainly in presynaptic terminals. It is predominantly expressed in the neocortex, hippocampus, striatum, thalamus, and cerebellum. beta-Synuclein may protect the central nervous system from the neurotoxic effects of alpha-synuclein by inhibiting aggregation of alpha-synuclein which occurs in neurodegenerative diseases such as Parkinson's disease. gamma-Synuclein is a synuclein protein found primarily in the peripheral nervous system (in primary sensory neurons, sympathetic neurons, and motor neurons) and retina. gamma-Synuclein expression in breast tumors is a marker for tumor progression.||Source:|Recombinant corresponding to aa1-134 with N-His tagm from human beta-synuclein, expressed in E. coli.||Molecular Weight:|~16.6kD||Storage and Stability:|Lyophilized powder may be stored at -20°C.
