CC   -!- FUNCTION: Tropomyosin, in association with the troponin complex, plays
CC       a central role in the calcium dependent regulation of muscle
CC       contraction. {ECO:0000250|UniProtKB:Q22866}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:A2V735}.
CC   -!- DOMAIN: The molecule is in a coiled coil structure that is formed by 2
CC       polypeptide chains. The sequence exhibits a prominent seven-residues
CC       periodicity. {ECO:0000305}.
CC   -!- ALLERGEN: Causes an allergic reaction in human. Binds to IgE of
CC       patients allergic to shellfish (mollusks and crustaceans).
CC       {ECO:0000269|PubMed:11246417}.
CC   -!- SIMILARITY: Belongs to the tropomyosin family. {ECO:0000305}.
