The protein expressed by the SNCA gene is involved in various synaptic activities, including the regulation of synaptic vesicle trafficking and neurotransmitter release. As a monomer, it enhances synaptic vesicle exocytosis through vesicle priming, fusion, and dilation of exocytotic fusion pores. Mechanistically, it increases local Ca(2+) release, which is crucial for ATP-induced exocytosis. In its multimeric membrane-bound form, SNCA acts as a molecular chaperone, assisting in the folding of synaptic fusion components known as SNAREs at the presynaptic plasma membrane, in conjunction with cysteine string protein-alpha/DNAJC5, a function that is vital for maintaining normal SNARE-complex assembly during aging. Additionally, SNCA plays a role in dopamine neurotransmission regulation by associating with the dopamine transporter (DAT1) and modulating its activity.

Belongs to the synuclein family.
Phosphorylated, predominantly on serine residues. Phosphorylation by CK1 appears to occur on residues distinct from the residue phosphorylated by other kinases. Phosphorylation of Ser-129 is selective and extensive in synucleinopathy lesions. In vitro, phosphorylation at Ser-129 promoted insoluble fibril formation. Phosphorylated on Tyr-125 by a PTK2B-dependent pathway upon osmotic stress.

Protocol FAQ

A: Please check our recommended Thioflavin T Fluorescence assay here
Alpha-synuclein often referred to by alternate names such as SNCA is a protein of around 14 kDa mass. It mainly expresses in the brain particularly in presynaptic nerve terminals. This protein functions mechanically by stabilizing synaptic vesicles and maintaining synaptic function. It exists both in soluble monomer forms and as aggregates in protein filaments. Antibodies like 4D6 and EP1536Y target monomer forms of protein for more detailed studies.
The alpha-synuclein protein plays critical roles in neuronal activity. It contributes to neurotransmitter release regulation by acting in the formation and plasticity of the presynaptic neuronal network. Alpha-synuclein doesn't usually form parts of large protein complexes but it may associate transiently with membranes and vesicular structures. The protein's monomer form has also been observed in alpha lines and related neuronal processes operating alongside various cellular functions.
Synaptic vesicle trafficking and dopamine neurotransmitter release are significant areas involving the alpha-synuclein protein. In these pathways alpha-synuclein interacts with other proteins like synaptophysin and protein monomer monomerizations are intrinsic to these processes. Altered function or aggregation of alpha-synuclein disrupts these pathways influencing broader neurological functions.
Alterations or accumulations of alpha-synuclein are strongly linked to Parkinson's disease and Lewy body dementia. In these conditions alpha-synuclein forms abnormal protein filaments known as Lewy bodies within neurons. These formations disrupt cellular processes and neuron health. Synucleinopathies such as these show connections with proteins like parkin and DJ-1 which also have key roles in these neurodegenerative diseases.
