paramyosin
Protein (200-220 kD) that forms a core in the thick filaments of invertebrate muscles. The molecule is rather like the rod part of myosin and has a two-chain coiled-coil a- helical structure, 130 x 2nm. Paramyosin is present in particularly high concentration in the "catch" muscle of bivalve molluscs, where it forms the almost crystalline core of the thick filaments.
