Surface structure and properties of plant seed oil bodies
Storage triacylglycerols (TAG) in plant seeds are present in small discrete intracellular organelles called oil bodies. An oil body has a matrix of TAG, which is surrounded by phospholipids (PL) and… Expand

Oil bodies are lipid storage organelles which have been analyzed biochemically due to the economic importance of oil seeds. Although oil bodies are structurally simple, the mechanisms involved in… Expand
Characterization of the charged components and their topology on the surface of plant seed oil bodies.
Oil bodies of plant seeds contain a triacylglycerol matrix surrounded by a monolayer of phospholipids embedded with alkaline proteins called oleosins. Oil bodies isolated from maize (Zea mays L.) in… Expand
Roles of Rho-associated Kinase and Myosin Light Chain Kinase in Morphological and Migratory Defects of Focal Adhesion Kinase-null Cells*

Fibroblasts derived from focal adhesion kinase (FAK)-null mouse embryos have a reduced migration rate and an increase in the number and size of peripherally localized adhesions (Ilic, D., Furuta, Y.,… Expand
Oleosin isoforms of high and low molecular weights are present in the oil bodies of diverse seed species.
Oleosins are unique and major proteins localized on the surface of oil bodies in diverse seed species. We purified five different oleosins (maize [Zea mays L.] KD 16 and KD 18, soybean [Glycine max… Expand
