Phl p 2 is a protein found in timothy grass pollen, which a common cause of seasonal allergies. This model shos Phl p 2 bound to a human IgE antibody that plays a key role in triggering allergic reactions. By visualizing how the allergen and antibody fit together, researchers can better understand how the immune system responds to pollen and explore ways to reduce or block allergic symptoms.
