Dystrobrevin Binding Protein 1 (DTNBP1)

Dysbindin is a protein constituent of the dystrophin-associated protein complex (DPC) of skeletal muscle cells. It is also a part of BLOC-1, or biogenesis of lysosome-related organelles complex 1. Dysbindin was discovered by the research group of Derek Blake via yeast two-hybrid screening for binding partners of α-dystrobrevin. In addition, dysbindin is found in neural tissue of the brain, particularly in axon bundles and especially in certain axon terminals, notably mossy fiber synaptic terminals in the cerebellum and hippocampus.Probable dysbindin-related mechanisms causing brain dysfunction are not fully known, but in one study, schizophrenic patients carrying the high-risk haplotype demonstrated visual processing deficits. In another work, damping down the DTNBP1 expression led to an increase in cell surface dopamine D2-receptor levels.
