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.
  • TISSUE SPECIFICITY: Aleurone (external part) of the seeds.
  • SIMILARITY: Belongs to the plant LTP family.
  • CAUTION: Was originally thought to be an inhibitor of alpha-amylase or of a protease and was known as PAPI: probable alpha-amylase/protease inhibitor.
