Alpha-synuclein is a presynaptic neuronal protein implicated in the pathogenesis of several neurodegenerative diseases, including Parkinson’s disease and dementia with Lewy bodies. Among its structural domains, the N-terminal region plays a pivotal role in membrane binding, conformational dynamics, and aggregation behavior. Post-translational modifications, particularly C-terminal truncations, significantly influence alpha-synuclein’s aggregation propensity and neurotoxicity (1). C-terminally truncated alpha-synuclein species are highly enriched in pathological inclusions such as Lewy bodies and Lewy neurites. These truncated forms exhibit accelerated fibrillization and enhanced prion-like propagation in cellular and animal models of Parkinson’s disease, underscoring their pathogenic relevance (1). Importantly, such truncations can alter the structural conformation of alpha-synuclein, masking epitopes commonly targeted by antibodies, including those recognizing phosphorylated serine 129 (pSer129). This epitope masking has critical implications for research and diagnostics. Antibodies specific to pSer129 may fail to detect C-terminally truncated alpha-synuclein, potentially underestimating the burden of pathogenic species in tissue samples. Therefore, careful selection of antibodies that target the N-terminal region is essential for accurate detection and quantification of disease-relevant alpha-synuclein conformers (3). Understanding the structural and functional roles of the alpha-synuclein N-terminus is vital for elucidating disease mechanisms and developing targeted therapeutic strategies in synucleinopathies. This antibody is also available conjugated to ATTO 390, ATTO 488, ATTO 594, APC, Biotin, FITC, HRP, PerCP and RPE. Supplied in 100 µg.
