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   -!- TISSUE SPECIFICITY: Expressed in muscle (at protein level).
CC       {ECO:0000269|PubMed:17263503, ECO:0000269|Ref.3}.
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 crustaceans (PubMed:17263503, Ref.3,
CC       PubMed:23840718). Heating increases IgE-binding activity. Cross-reacts
CC       with blue swimmer crab tropomyosin allergen Por p 1.0101. Recombinant
CC       protein causes activation of basophils (PubMed:23840718).
CC       {ECO:0000269|PubMed:17263503, ECO:0000269|PubMed:23840718,
CC       ECO:0000269|Ref.3}.
CC   -!- SIMILARITY: Belongs to the tropomyosin family. {ECO:0000255}.
