Summary: Predicted to enable metal ion binding activity and tubulin binding activity. Involved in synaptic vesicle endocytosis. Acts upstream of or within several processes, including chemical synaptic transmission; dopamine metabolic process; and negative regulation of neuron apoptotic process. Located in synapse. Is expressed in central nervous system; peripheral nervous system; retina; stomach; and testis. Human ortholog(s) of this gene implicated in Lewy body dementia and Parkinson's disease. Orthologous to human SNCB (synuclein beta). [provided by Alliance of Genome Resources, Apr 2022]

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.
