In Western blot, ab212184 was shown to bind specifically to Alpha-synuclein. A band was observed at 16 kDa in wild-type U-87 MG cell lysates with no signal observed at this size in SNCA knockout cell line ab282333 (knockout cell lysate ab283006). To generate this image, wild-type and SNCA knockout U-87 MG cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4°C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged.

Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

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.
Biological function summary

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.

Pathways

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.

Target data

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. This supplementary information is collated from multiple sources and compiled automatically.
