Research Backgrounds

Function:

Neuronal protein that plays several roles in synaptic activity such as regulation of synaptic vesicle trafficking and subsequent neurotransmitter release. Participates as a monomer in synaptic vesicle exocytosis by enhancing vesicle priming, fusion and dilation of exocytotic fusion pores. Mechanistically, acts by increasing local Ca(2+) release from microdomains which is essential for the enhancement of ATP-induced exocytosis. Acts also as a molecular chaperone in its multimeric membrane-bound state, assisting in the folding of synaptic fusion components called SNAREs (Soluble NSF Attachment Protein REceptors) at presynaptic plasma membrane in conjunction with cysteine string protein-alpha/DNAJC5. This chaperone activity is important to sustain normal SNARE-complex assembly during aging. Plays also a role in the regulation of the dopamine neurotransmission by associating with the dopamine transporter (DAT1) and thereby modulating its activity.

PTMs:

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.

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 (By similarity).

Acetylation at Met-1 seems to be important for proper folding and native oligomeric structure.

Tissue Specificity:

Highly expressed in presynaptic terminals in the central nervous system. Expressed principally in brain.

Subunit Structure:

Soluble monomer. Homotetramer. A dynamic intracellular population of tetramers and monomers coexists normally and the tetramer plays an essential role in maintaining homeostasis. Interacts with UCHL1 (By similarity). Interacts with phospholipase D and histones. Interacts (via N-terminus) with synphilin-1/SNCAIP; this interaction promotes formation of SNCA inclusions in the cytoplasm. Interacts with CALM1. Interacts with STXBP1; this interaction controls SNCA self-replicating aggregation. Interacts with SNARE components VAMP2 and SNAP25; these interactions allows SNARE complex assembly and integrity. Interacts with RPH3A and RAB3A. Interacts with SERF1A; this interaction promotes the aggregation of SNCA.

Family&Domains:

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.

Belongs to the synuclein family.
