Summary: Enables arachidonate binding activity; histone binding activity; and identical protein binding activity. Involved in several processes, including protein-containing complex assembly; regulation of reactive oxygen species metabolic process; and synaptic vesicle endocytosis. Acts upstream of or within several processes, including chemical synaptic transmission; modulation of chemical synaptic transmission; and regulation of amine transport. Located in several cellular components, including axon terminus; inclusion body; and neuronal cell body. Is active in synaptic vesicle membrane. Is expressed in several structures, including central nervous system; future brain; genitourinary system; sensory ganglion; and sensory organ. Used to study Parkinson's disease 1 and Parkinson's disease 4. Human ortholog(s) of this gene implicated in Alzheimer's disease; Lewy body dementia; Parkinson's disease; Parkinson's disease 1; and Parkinson's disease 4. Orthologous to human SNCA (synuclein alpha). [provided by Alliance of Genome Resources, Jul 2025]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
