Plant non-specific lipid-transfer proteins transfer phospholipids as well as galactolipids across membranes. May play a role in wax or cutin deposition in the cell walls of expanding epidermal cells and certain secretory tissues. Expressed in protoderm cells of somatic and zygotic embryos, and transiently expressed in epidermal cell layers of leaves, flowers and seeds. Belongs to the plant LTP family.
