Biogenesis of lysosome-related organelles complex 1 subunit 2 (Bloc1s2)

Part 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 (By similarity). In concert with the AP-3 complex, the BLOC-1 complex is needed to target membrane protein cargos to vesicles constructed at cell bodies for delivery to neurites and nerve terminals (PubMed:16760431, PubMed:21998198).

The BLOC-1 complex, in association with SNARE proteins, is also proposed to be involved in neurite extension (PubMed:19546860). As part of the BORC complex may play a role in lysosomes motion and localization in the cell periphery.
