Function

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). 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 (PubMed:20798282). This chaperone activity is important to sustain normal SNARE-complex assembly during aging (PubMed:20798282). Also plays a role in the regulation of the dopamine neurotransmission by associating with the dopamine transporter (DAT1) and thereby modulating its activity (PubMed:26442590).

Activity summary

Alpha-synuclein aggregates are critical in the study of neurobiology. These aggregates form by accumulation of alpha-synuclein a protein that exists mostly in neural tissues. Also known as SNCA this protein has a mass of approximately 14 kDa. Researchers frequently find alpha-synuclein in presynaptic terminals of neurons but expression also occurs in the nucleus and cytoplasm of neuronal cells. This protein has a notable interaction with lipid membranes indicating its role in synaptic vesicle regulation.

Biological function summary

Alpha-synuclein manages several cellular processes most notably in neurotransmitter release and vesicle recycling. It does not work alone; it often forms complexes with other proteins like synaptobrevin-2 of the SNARE complex. The formation of these complexes allows for the proper functioning of synaptic vesicles. Alteration in alpha-synuclein's normal function through aggregation disrupts these processes which underlies many neural complications.

Pathways

Many neuronal functions depend on alpha-synuclein's participation in synaptic vesicle pathways. Key pathways include the dopamine metabolic pathway where alpha-synuclein regulates dopamine release. The protein interacts with other synaptic proteins like the SNARE proteins potentially affecting protein kinase pathways. Abnormal aggregation impacts these pathways which can propagate cellular stress and contribute to cellular degeneration.

Associated diseases and disorders

Alpha-synuclein aggregation correlates strongly with Parkinson's disease and Lewy body dementia. In these conditions aggregates form Lewy bodies protein clusters within neurons that impair their function and encourage neural degradation. The protein interacts with structural proteins like ubiquitin. Ubiquitin involvement highlights the importance of degradation pathways in these disorders as impaired proteostasis due to aggregated alpha-synuclein exacerbates disease progression.
