Comments Information

    • 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.

    • Induction

    • By cold.

    • PTM

    • Contains four disulfide bonds (By similarity).

Literature Information

  • ·Literature 1

    • Title

    • Two cold-inducible genes encoding lipid transfer protein LTP4 from barley show differential responses to bacterial pathogens.
