  • 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.
  • Tissue specificity
    Detected in brain, in neurons and in neuropil. Detected in dentate gyrus and in pyramidal cells of hippocampus CA2 and CA3 (at protein level).
  • Involvement in disease
    Defects in DTNBP1 are the cause of Hermansky-Pudlak syndrome type 7 (HPS7) [MIM:203300]. Hermansky-Pudlak syndrome (HPS) is a genetically heterogeneous, rare, autosomal recessive disorder characterized by oculocutaneous albinism, bleeding due to platelet storage pool deficiency, and lysosomal storage defects. This syndrome results from defects of diverse cytoplasmic organelles including melanosomes, platelet dense granules and lysosomes. Ceroid storage in the lungs is associated with pulmonary fibrosis, a common cause of premature death in individuals with HPS.
  • Sequence similarities
    Belongs to the dysbindin family.
  • Post-translational
    Ubiquitinated by TRIM32. Ubiquitination leads to DTNBP1 degradation.
    Phosphorylated by PRKDC.
  • Cellular localization
    Cytoplasm. Cytoplasmic vesicle membrane. Cytoplasmic vesicle > secretory vesicle > synaptic vesicle membrane. Endosome membrane. Melanosome membrane. Nucleus. Cell junction > synapse > postsynaptic cell membrane > postsynaptic density. Endoplasmic reticulum. Detected in neuron cell bodies, axons and dendrites. Detected at synapses, at post-synaptic density, at pre-synaptic vesicle membranes and microtubules. Detected at tubulovesicular elements in the vicinity of the Golgi apparatus and of melanosomes. Occasionally detected at the membrane of pigmented melanosomes in cultured melanoma cells.

  • All lanes : Anti-Dysbindin antibody (ab36646) at 1 µg/ml

    Lane 1 : Brain (Mouse) Tissue Lysate
    Lane 2 : Testis (Mouse) Tissue Lysate

    Lysates/proteins at 10 µg per lane.

    All lanes : Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/5000 dilution

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 40 kDa
    Observed band size: 50 kDa (why is the actual band size different from the predicted?)
    Additional bands at: 140 kDa, 35 kDa (possible isoform), 80 kDa. We are unsure as to the identity of these extra bands.

    Ab36646 detects a band at approximately 50-kDa. The Dysbindin protein sequence contains a potential ubiquitination site. This post-translational modification might explain the migration of the protein at a higher molecular weight than that predicted from the primary sequence (Swissprot). Abcam welcomes customer feedback and would appreciate any comments regarding this product and the data presented above.
