  • 功能：
    Component of the BLOC-1 complex, a complex that is required for normal biogenesis of lysosome-related organelles (LRO), such as platelet dense granules and melanosomes. In concert with the AP-3 complex, the BLOC-1 complex is required to target membrane protein cargos into vesicles assembled at cell bodies for delivery into neurites and nerve terminals. The BLOC-1 complex, in association with SNARE proteins, is also proposed to be involved in neurite extension. Associates with the BLOC-2 complex to facilitate the transport of TYRP1 independent of AP-3 function. Plays a role in synaptic vesicle trafficking and in neurotransmitter release. Plays a role in the regulation of cell surface exposure of DRD2. May play a role in actin cytoskeleton reorganization and neurite outgrowth. May modulate MAPK8 phosphorylation. Appears to promote neuronal transmission and viability through regulating the expression of SNAP25 and SYN1, modulating PI3-kinase-Akt signaling and influencing glutamatergic release. Regulates the expression of SYN1 through binding to its promoter. Modulates prefrontal cortical activity via the dopamine/D2 pathway.

    Defects in Dtnbp1 are the cause of the sandy (sdy) mutant phenotype, a model for human Hermansky-Pudlak syndrome (HPS). Sdy mice lack dysbindin expression; they have a characteristic sandy coat color and have much fewer melanosomes in the retinal pigment epithelium and choroid. They are fully viable, but present behavioral abnormalities. They have prolonged bleeding times due to platelet storage pool deficiency, and lysosomal storage defects. The number of electron-opaque platelet dense granules is severely reduced, and the platelet serotonin content is strongly reduced. Secretion of lysosomal enzymes from kidney and from thrombin-stimulated platelets is depressed 2- and 3-fold, and ceroid pigment is present in kidney. Sandy mice also display impaired long-term memory retention and working memory and schizophrenia-like behavioral abnormalities. Vesicle morphology and kinetics of transmitter release are affected in both neuroendocrine cells and hippocampal synapses, characterized by larger vesicle size, slower quantal release, fewer release events and reduced readily releasable pool (RRP). Expression levels of SYN1 are lower in both the cortex and the hippocampal formation (HF).
