Scientific Background | Alpha-synuclein (SNCA) is a neuronal protein predominantly expressed in the brain, where it is highly concentrated at presynaptic nerve terminals, suggesting a key role in synaptic transmission and plasticity (1). In addition to its synaptic localization, alpha-synuclein is abundantly expressed in mitochondria-rich brain regions, including the olfactory bulb, hippocampus, striatum, and thalamus, implicating it in mitochondrial function and energy metabolism (2). Functionally, alpha-synuclein has been shown to interact significantly with tubulin (3), indicating a potential role as a microtubule-associated protein involved in cytoskeletal organization and intracellular transport. This interaction may be critical for maintaining neuronal structure and function, particularly in long-range axonal projections. Importantly, alpha-synuclein is essential for normal cognitive development. Genetic or functional inactivation of SNCA has been associated with impairments in spatial learning and working memory, underscoring its role in higher-order brain functions (4). Given its physiological importance and pathological aggregation in disorders such as Parkinson’s disease and dementia with Lewy bodies, alpha-synuclein remains a focal point in neurodegenerative disease research. Understanding its normal function and mechanisms of misfolding is vital for developing targeted diagnostics and therapeutics. |
