Function
The BLOC-1 complex is required for normal biogenesis of lysosome-related organelles, such as platelet dense granules and melanosomes. Plays a role in intracellular vesicle trafficking. Plays a role in synaptic vesicle trafficking and in neurotransmitter release. May be required for normal dopamine homeostasis in the cerebral cortex, hippocampus, and hypothalamus. Plays a role in the regulation of cell surface exposure of DRD2. Contributes to the regulation of dopamine signaling. May play a role in actin cytoskeleton reorganization and neurite outgrowth. May modulate MAPK8 phosphorylation.
Specificity
Natural and recombinant Mouse Dysbindin

Part of the biogenesis of lysosome-related organelles complex 1 (BLOC-1). The BLOC-1 complex is composed of BLOC1S1, BLOC1S2, BLOC1S3, DTNBP1, MUTED, PLDN, CNO/cappuccino and SNAPIN. Interacts with AP3M1 and TRIM32 (By similarity). Interacts with the DNA-dependent protein kinase complex DNA-PK (By similarity). Identified in a complex with the biogenesis of lysosome-related organelles complex 2 (BLOC-2) (By similarity). Binds to DTNA and DTNB but may not be a physiological binding partner (PubMed:16448387 and PubMed:16980328). Interacts with AP3B2. Identified in a complex with the adapter-related protein complex 3 (AP-3). Interacts with RNF151 and CMYA5.
