Protein attributes

Sequence length	284 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Tropomyosin, in association with the troponin complex, plays a central role in the calcium dependent regulation of muscle contraction.
Domain	The molecule is in a coiled coil structure that is formed by 2 polypeptide chains. The sequence exhibits a prominent seven-residues periodicity.
Allergenic properties	Causes an allergic reaction in human. Binds to IgE. A.simplex is a fish parasite that, when accidentally ingested by humans, may cause allergic reactions in sensitized individuals.
Sequence similarities	Belongs to the tropomyosin family.
