Plant non-specific lipid-transfer proteins transfer phospholipids as well as galactolipids across membranes (By similarity). May play a role in wax or cutin deposition in the cell walls of expanding epidermal cells and certain secretory tissues (By similarity). Binds to both saturated and unsaturated lipids, with the highest binding efficiency for linoleic acid, followed by linolenic acid (PubMed:33277525). Expressed in seeds (at protein level). Belongs to the plant LTP family.
