Background: alpha-Synuclein

Synuclein-alpha is a 14 kDa member of the synuclein family. It is found in both the neuron nucleus and the cytosol of presynaptic nerve terminals in the brain. Synuclein-alpha is 140 amino acids in length and runs anomalously at 19 kDa in SDS-page. It contains three domains; an N-terminal lipid-binding domain, a central amyloid-binding region, and a C-terminal acidic tail. The N-terminal area (aa 1 - 100) is involved with lipid (membrane) and protein binding. The C-terminus may be regulatory. There is a NAC (non-Ab component of AD amyloid) segment between aa 61 - 95. This has been thought to mediate synuclein-alpha filament formation and microtubial stabilization. Whether it exists as a stand-alone normal cleavage product of synuclein-alpha is unclear. Synuclein-alpha is phosphorylated on multiple sites. S129 undergoes constitutive phosphorylation and dephosphorylation. When phosphorylated, filament formation (and perhaps oligomerization) is promoted. Uncontrolled filament/fibril formation is suggested to be involved in Parkinson’s disease Lewy body formation. Tyrosine phosphorylation also occurs at Y125. Synuclein-alpha is known to bind to, and inhibit, PLD-1 and -2. When phosphorylated at Y125, synuclein-alpha activity is decreased and PLD activity is increased.
