Protein existence	Evidence at protein level

General annotation (Comments)

Function	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 By similarity.
Allergenic properties	Causes an allergic reaction in human. Binds to IgE. Ref.1
Sequence similarities	Belongs to the plant LTP family.
Mass spectrometry	Molecular mass is 9646 Da from positions 1 - ?. Determined by MALDI. Ref.1
