Many of the major pollen coat proteins are derived from endoproteolytic cleavage of oleosin-like proteins. Surface of oil bodies. Oleosins exist at a monolayer lipid/water interface (By similarity). The full-length protein is found in the tapetal lipid bodies of immature anthers, the proteolytically cleaved C-terminal product is found on the coats of pollen grains. Not found in flowers, developing embryos or leaf tissue. Only found in buds 3-5 mm long. Belongs to the oleosin family.
