Tropomyosin
From Freepedia
A tropomyosin is any of a group of muscle proteins that bind to molecules of actin and troponin to regulate the interaction of actin and myosin.
Certain tropomyosins are known to cause allergies in certain people, and those who have cross-reactive allergies can get symptons from a range of sources due to a common allergen found in all these sources. Common allergies include shrimp, dust mites and mollusks.
