...Glenn E. White; Christine M. Petry; Fred Schachat SUMMARY Examination of null mutants in myosin B and paramyosin yields insights into the complex mechanisms that regulate expression of the three major components of Caenorhabditis elegans body-wall muscle thick filaments myosin A,myosin B...

... primarily through changes in the dimensions and arrangement of the myofilament lattice, rather than through changes in biochemistry. The thick filament core protein paramyosin was tentatively identified in the squid muscle fibres. This protein was less abundant in the short thick filament cross-striated...
