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 (Probable). Binds saturated and unsaturated lipids, jasmonic acid and lysolipids (PubMed:27137920). Has antifungal activity against A.niger VKM F-2259 (IC(50)=40 uM), F.oxysporum TCXA-4 (IC(50)=20-40), F.solani VKM F-142 (IC(50)=20-40 uM) and N.crassa VKM F-184 (IC(50)=40 uM) (PubMed:27137920). Has weak antibacterial activity against A.tumefaciens A281, C.michiganensis VKM Ac-1144 and P.syringae VKM B-1546 (PubMed:27137920). Expressed in roots, stem, leaves and tendrils of the mature plant. Expression drops sharply after germination and increases again in the mature plant. Causes an allergenic reaction in human. Binds to IgE. Belongs to the plant LTP family.
