[[http://www.uniprot.org/uniprot/RAB1B_HUMAN RAB1B_HUMAN]] Protein transport. Regulates vesicular transport between the endoplasmic reticulum and successive Golgi compartments.<ref>PMID:9437002</ref> [[http://www.uniprot.org/uniprot/Q5ZSQ3_LEGPH Q5ZSQ3_LEGPH]] Virulence effector that plays a key role in hijacking the host vesicular trafficking by recruiting the small guanosine triphosphatase (GTPase) Rab1 to the cytosolic face of the Legionella-containing vacuole (LCVs). Acts as a GDP-GTP exchange factor (GEF) for the small GTPase Rab1 (RAB1A, RAB1B or RAB1C), thereby converting Rab1 to an active GTP-bound state, leading to the incorporation of Rab1 into LCVs. Also shows RabGDI displacement factor (GDF) activity; however, this probably represents a passive activity following the GEF activity. Also acts as an adenylyltransferase by mediating the addition of adenosine 5'-monophosphate (AMP) to 'Tyr-77' of host RAB1B, thereby rendering RAB1B constitutively active. Also has adenylyltransferase activity towards Rab6 and Rab35. Also displays guanylyltransferase activity by mediating the addition of guanosine 5'-monophosphate (GMP) to host RAB1B in vitro; however such activity remains uncertain in vivo. Specifically binds phosphatidylinositol 4-phosphate (PtdIns(4)P) lipids on the cytosolic surface of the phagosomal membrane shortly after infection.<ref>PMID:16824952</ref><ref>PMID:17947549</ref><ref>PMID:21822290</ref><ref>PMID:20064470</ref><ref>PMID:19942850</ref><ref>PMID:20176951</ref>
