rab-11.1 encodes a small GTPase homologous to the Rab GTPases that function in endocytosis, membrane fusion, and vesicular trafficking events; RAB-11.1 activity is required for completion of the final stages of cytokinesis during early embryogenesis and for efficient uptake of yolk proteins during oocyte development; RAB-11.1 is also required for normal peripheral localization of nuclei in the synctial germ cell in the ovary and for regulated secretion of CAV-1-containing cortical granules following fertilization; RAB-11.1 localizes to recycling endosomes and to cortical granules.
Predicted to enable GTP binding activity and GTPase activity. Involved in several processes, including eggshell formation; membrane addition at site of mitotic cytokinesis; and vesicle-mediated transport. Located in Golgi trans cisterna membrane; cortical granule; and recycling endosome. Expressed in gonad. Is an ortholog of human RAB11A (RAB11A, member RAS oncogene family).
