Cytoplasm, perinuclear region {ECO:0000269|PubMed:16750429}. Membrane {ECO:0000250|UniProtKB:Q86WG5}; Peripheral membrane protein {ECO:0000250|UniProtKB:Q86WG5}. Endosome membrane {ECO:0000269|PubMed:23297362}; Peripheral membrane protein {ECO:0000305}. Cell projection, axon {ECO:0000269|PubMed:23297362}. Note=Associated with membranes (By similarity). Localizes to vacuoles in hypo-osmotic conditions (PubMed:16399794). Membrane localization is likely to be mediated via its interaction with MTMR2 (PubMed:23297362). {ECO:0000250|UniProtKB:Q86WG5, ECO:0000269|PubMed:16399794, ECO:0000269|PubMed:23297362}.

Promotes the exchange of GDP to GTP, converting inactive GDP-bound Rab proteins into their active GTP-bound form (By similarity). In response to starvation-induced autophagy, activates RAB21 which in turn binds to and regulates SNARE protein VAMP8 endolysosomal transport required for SNARE-mediated autophagosome-lysosome fusion (By similarity). Acts as an adapter for the phosphatase MTMR2 (PubMed:16399794). Increases MTMR2 catalytic activity towards phosphatidylinositol 3,5-bisphosphate and to a lesser extent towards phosphatidylinositol 3-phosphate (PubMed:16399794). {ECO:0000250|UniProtKB:Q86WG5, ECO:0000269|PubMed:16399794}.
