The function of Ensembl gene identifier ENSG00000196072 (BLOC1S2, biogenesis of lysosomal organelles complex 1 subunit 2) is as follows. 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 (PubMed:15102850, PubMed:17182842). 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 (By similarity). As part of the BORC complex may play a role in lysosomes movement and localization at the cell periphery. Associated with the cytosolic face of lysosomes, the BORC complex may recruit ARL8B and couple lysosomes to microtubule plus-end-directed kinesin motor (PubMed:25898167). May play a role in cell proliferation (PubMed:15381421). {ECO:0000250|UniProtKB:Q9CWG9, ECO:0000269|PubMed:15102850, ECO:0000269|PubMed:15381421, ECO:0000269|PubMed:17182842, ECO:0000269|PubMed:25898167}.
