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. Thereby, it may indirectly play a role in cell spreading and motility. Component of the BLOC-one-related complex (BORC) which is composed of BLOC1S1, BLOC1S2, BORCS5, BORCS6, BORCS7, BORCS8, KXD1 and SNAPIN (PubMed:25898167). Interacts with ARL8B, KIF5A, KLC1 and PLEKHM2; links the lysosomal BORC complex to the microtubule plus-end-directed kinesin motor (PubMed:25898167). Ubiquitously expressed (at protein level). Myristoylation at Gly-2 mediates attachment to lysosome membranes. Belongs to the BORCS5 family.
