Predicted to enable actin filament binding activity. Predicted to be a structural constituent of synapse. Involved in cellular response to ethanol and synaptic vesicle exocytosis. Located in several cellular components, including Golgi membrane; cytoplasmic vesicle; and perinuclear region of cytoplasm. Human ortholog(s) of this gene implicated in autosomal recessive spinocerebellar ataxia 14 and spinocerebellar ataxia type 5. Orthologous to human SPTBN2 (spectrin beta, non-erythrocytic 2).
