    • Function

    • Main toxin of bee venom with strong hemolytic activity. Forms a pore in the cell membrane by inserting into lipid bilayers in an alpha-helical conformation and has multiple effects, probably, as a result of its interaction with negatively charged phospholipids. It inhibits well known transport pumps such as the Na+-K+-ATPase and the H+-K+-ATPase. It increases the permeability of cell membranes to ions, particularly Na+ and indirectly Ca2+, because of the Na+-Ca2+-exchange. It acts synergistically with phospholipase A2.
