CC -!- FUNCTION: May play a role in lysosome motility. May play a role in CC chromosome segregation. {ECO:0000250|UniProtKB:Q9NVJ2}. CC -!- FUNCTION: (Microbial infection) Component of tomato mosaic virus (ToMV) CC RNA replication complexes. Required for tobamovirus multiplication, CC especially for efficient negative-strand RNA synthesis and viral RNA CC capping. {ECO:0000269|PubMed:22174675}. CC -!- SUBUNIT: Interacts with tubulin. {ECO:0000250|UniProtKB:Q9NVJ2}. CC -!- SUBCELLULAR LOCATION: Late endosome membrane CC {ECO:0000250|UniProtKB:Q9NVJ2}. Lysosome membrane CC {ECO:0000250|UniProtKB:Q9NVJ2}. Cytoplasm, cytoskeleton, spindle CC {ECO:0000250|UniProtKB:Q9NVJ2}. Note=Localizes with microtubules at the CC spindle mid-zone during mitosis. {ECO:0000250|UniProtKB:Q9NVJ2}. CC -!- DISRUPTION PHENOTYPE: In double and triple mutants arl8a-1 arl8b-1 and CC arl8a-1 arl8b-1 arl8c-1, impaired multiplication of tomato mosaic virus CC (ToMV) associated with reduced production of negative-strand RNA. CC {ECO:0000269|PubMed:22174675}. CC -!- SIMILARITY: Belongs to the small GTPase superfamily. Arf family. CC {ECO:0000305}.
