WebNeuronal α-synuclein is concentrated in presynapt ic nerve terminals, interacts with plasma membrane phospholipids, and is also present in nuclei and mitochondria. At least three isoforms of α-synuclein are produced through alternative splicing. The most common isoform is a 140 amino acid-long transcript.
