Target
-
Function
May be involved in the regulation of dopamine release and transport. Induces fibrillization of microtubule-associated protein tau. Reduces neuronal responsiveness to various apoptotic stimuli, leading to a decreased caspase-3 activation. -
Tissue specificity
Expressed principally in brain but is also expressed in low concentrations in all tissues examined except in liver. Concentrated in presynaptic nerve terminals. -
Involvement in disease
Genetic alterations of SNCA resulting in aberrant polymerization into fibrils, are associated with several neurodegenerative diseases (synucleinopathies). SNCA fibrillar aggregates represent the major non A-beta component of Alzheimer disease amyloid plaque, and a major component of Lewy body inclusions. They are also found within Lewy body (LB)-like intraneuronal inclusions, glial inclusions and axonal spheroids in neurodegeneration with brain iron accumulation type 1.
Parkinson disease 1
Parkinson disease 4
Dementia Lewy body -
Sequence similarities
Belongs to the synuclein family. -
Domain
The 'non A-beta component of Alzheimer disease amyloid plaque' domain (NAC domain) is involved in fibrils formation. The middle hydrophobic region forms the core of the filaments. The C-terminus may regulate aggregation and determine the diameter of the filaments. -
Post-translational
modificationsPhosphorylated, 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.
Hallmark lesions of neurodegenerative synucleinopathies contain alpha-synuclein that is modified by nitration of tyrosine residues and possibly by dityrosine cross-linking to generated stable oligomers.
Ubiquitinated. The predominant conjugate is the diubiquitinated form.
Acetylation at Met-1 seems to be important for proper folding and native oligomeric structure. -

Lane 1: Wild type HAP1 whole cell lysate (40 µg)
Lane 2: SNCA knockout HAP1 whole cell lysate (40 µg)
Lane 3: Human brain tissue lysate (40 µg)
Lane 4: Mouse brain tissue lysate (40 µg)Lanes 1 - 4: Merged signal (red and green). Green - ab93432 observed at 14 kDa. Red - loading control, ab8245, observed at 37 kDa.
ab93432 was shown to specifically react with SNCA in wild-type HAP1 cells along with additional cross reactive bands. No bands were observed when SNCA knockout samples were used. Wild-type and SNCA knockout samples were subjected to SDS-PAGE. ab93432 and ab8245 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 1 dilution and 1/10000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.

Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 14 kDa
Observed band size: 17 kDa why is the actual band size different from the predicted?
Exposure time: 8 minutes
Ab934432 detects a band at 17-kDa. While this differs to its predicted molecular weight of 14-kDa, this migration has been observed in the literature (PMID:12042811). -
ICC/IF image of ab93432 stained SKNSH cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab93432, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
