CC   -!- FUNCTION: May have a structural role to stabilize the lipid body during
CC       desiccation of the seed by preventing coalescence of the oil. Probably
CC       interacts with both lipid and phospholipid moieties of lipid bodies.
CC       May also provide recognition signals for specific lipase anchorage in
CC       lipolysis during seedling growth.
CC   -!- SUBCELLULAR LOCATION: Lipid droplet. Membrane; Multi-pass membrane
CC       protein. Note=Surface of oil bodies. Oleosins exist at a monolayer
CC       lipid/water interface.
CC   -!- SIMILARITY: Belongs to the oleosin family. {ECO:0000305}.
