Synucleins are small proteins that are highly expressed in brain tissue and are localised at presynaptic terminals in neurons. α-Synuclein has been identified as a component of intracellular fibrillar protein deposits in several neurodegenerative diseases, and two mutant forms of α-synuclein have been associated with autosomal-dominant Parkinson's Disease. A fragment of α-synuclein has also been identified as the non-Aβ component of Alzheimer's Disease amyloid. In this review we describe some structural properties of α-synuclein and the two mutant forms, as well as α-synuclein fragments, with particular emphasis on their ability to form β-sheet on ageing and aggregate to form amyloid-like fibrils. Differences in the rates of aggregation and morphologies of the fibrils formed by α-synuclein and the two mutant proteins are high-lighted. Interactions between α-synuclein and other proteins, especially those that are components of amyloid or Lewy bodies, are considered. The toxicity of α-synuclein and related peptides towards neurons is also discussing in relation to the aetiology of neurodegenerative diseases. (C) 2000 Academic Press.
