CC   -!- FUNCTION: Component of the BLOC-1 complex, a complex that is required
CC       for normal biogenesis of lysosome-related organelles (LRO), such as
CC       platelet dense granules and melanosomes. In concert with the AP-3
CC       complex, the BLOC-1 complex is required to target membrane protein
CC       cargos into vesicles assembled at cell bodies for delivery into
CC       neurites and nerve terminals. The BLOC-1 complex, in association with
CC       SNARE proteins, is also proposed to be involved in neurite extension.
CC       Plays a role in intracellular vesicle trafficking.
CC       {ECO:0000269|PubMed:16385460, ECO:0000269|PubMed:17182842}.
CC   -!- SUBUNIT: Interacts with BLOC1S4, BLOC1S5 and BLOC1S6 (By similarity).
CC       Component of the biogenesis of lysosome-related organelles complex 1
CC       (BLOC-1) composed of BLOC1S1, BLOC1S2, BLOC1S3, BLOC1S4, BLOC1S5,
CC       BLOC1S6, DTNBP1/BLOC1S7 and SNAPIN/BLOC1S8. Octamer composed of one
CC       copy each BLOC1S1, BLOC1S2, BLOC1S3, BLOC1S4, BLOC1S5, BLOC1S6,
CC       DTNBP1/BLOC1S7 and SNAPIN/BLOC1S8. The BLOC-1 complex associates with
CC       the AP-3 protein complex and membrane protein cargos. Interacts
CC       directly with BLOC1S2. {ECO:0000250, ECO:0000269|PubMed:15102850,
CC       ECO:0000269|PubMed:22203680}.
CC   -!- INTERACTION:
CC       Q6QNY0; Q6QNY1: BLOC1S2; NbExp=3; IntAct=EBI-465930, EBI-465872;
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- DISEASE: Hermansky-Pudlak syndrome 8 (HPS8) [MIM:614077]: A form of
CC       Hermansky-Pudlak syndrome, a genetically heterogeneous autosomal
CC       recessive disorder characterized by oculocutaneous albinism, bleeding
CC       due to platelet storage pool deficiency, and lysosomal storage defects.
CC       This syndrome results from defects of diverse cytoplasmic organelles
CC       including melanosomes, platelet dense granules and lysosomes. Ceroid
CC       storage in the lungs is associated with pulmonary fibrosis, a common
CC       cause of premature death in individuals with HPS.
CC       {ECO:0000269|PubMed:16385460}. Note=The disease is caused by variants
CC       affecting the gene represented in this entry.
CC   -!- SIMILARITY: Belongs to the BLOC1S3 family. {ECO:0000305}.
