== Function ==
[https://www.uniprot.org/uniprot/MYH7_PIG MYH7_PIG] Myosins are actin-based motor molecules with ATPase activity essential for muscle contraction. Forms regular bipolar thick filaments that, together with actin thin filaments, constitute the fundamental contractile unit of skeletal and cardiac muscle.[UniProtKB:P12883]
