Also known as synuclein, alpha (non A4 component of amyloid precursor), synuclein alpha-140, truncated alpha synuclein, Non-A4 component of amyloid precursor, SNCA, Non-A beta component of AD amyloid, non A-beta component of AD amyloid, alpha-synuclein

Alpha-synuclein (aSyn) is a protein that in humans is encoded by the SNCA gene. It is a neuronal protein involved in the regulation of synaptic vesicle trafficking and the release of neurotransmitters.

Neuronal protein that plays several roles in synaptic activity such as regulation of synaptic vesicle trafficking and subsequent neurotransmitter release (PubMed:20798282, PubMed:26442590, PubMed:28288128, PubMed:30404828). Participates as a monomer in synaptic vesicle exocytosis by enhancing vesicle priming, fusion and dilation of exocytotic fusion pores (PubMed:28288128, PubMed:30404828). Mechanistically, acts by increasing local Ca(2+) release from microdomains which is essential for the enhancement of ATP-induced exocytosis (PubMed:30404828). Also acts as a molecular chaperone in its mu…

α-シヌクレイン (あるふぁ-しぬくれいん) はSNCA 遺伝子によってエンコードされるアミノ酸140残基からなるタンパク質。 このタンパクの断片が、アルツハイマー病に蓄積するアミロイド中の (主な構成成分であるアミロイドベータとは別の) 成分として発見され、もとのタンパク質がNACP (Non-Abeta component precursor 非アミロイド成分の前駆体) と命名された。後にこれがシビレエイ属のシヌクレインタンパクと相同であることがわかり、ヒトα-シヌクレインと呼ばれるようになった。 α-シヌクレインの蓄積は、パーキンソン病をはじめとする神経変性疾患 (いわゆるシヌクレイノパチー) の原因とされている。
