Involved in several processes, including negative regulation of dendritic spine morphogenesis; positive regulation of transport; and regulation of dopamine receptor signaling pathway. Located in several cellular components, including dendritic spine; neuronal cell body; and synaptic vesicle membrane. Biomarker of temporal lobe epilepsy. Human ortholog(s) of this gene implicated in Hermansky-Pudlak syndrome 7 and schizophrenia. Orthologous to human DTNBP1 (dystrobrevin binding protein 1).
