function:May play a role in lysosomes motility (PubMed:16537643). May play a role in chromosomes segregation (PubMed:15331635).,similarity:Belongs to the small GTPase superfamily. Arf family.,subcellular location:According to PubMed:15331635 it localizes with microtubules at the spindle mid-zone during mitosis.,subunit:Interacts with tubulin.,tissue specificity:Ubiquitously expressed.,
Late endosome membrane . Lysosome membrane . Cytoplasm, cytoskeleton, spindle . Cell projection, axon . Cell junction, synapse . Cytolytic granule membrane . GTP-bound form resides on lysosomal membranes, whereas GDP-bound form is likely associated with microtubular structures (PubMed:16650381). Localizes with microtubules at the spindle mid-zone during mitosis. In dendritic cells, localizes to MHC II+ compartments (By similarity). .
Ubiquitously expressed.
