通过鱿鱼肌球蛋白与鱿鱼肌球蛋白B的竞争试验、鱿鱼肌球蛋白与肌动蛋白、鲤鱼肌球蛋白与鱿鱼细丝部分的交叉结合试验，研究了鱿鱼肌肉蛋白对钙离子的敏感性。结果表明，与骨骼肌一样，鱿鱼外套肌的调节系统是肌动蛋白连接的，而不是肌球蛋白连接的。这一观点得到了鱿鱼细丝组分的SDS-圆盘电泳图上肌钙蛋白样组分的支持。
Ca2+-sensitivity of squid muscle proteins was studied by competition tests between squid actin and carp myosin on squid myosin B and by cross combination tests between squid myosin and actin and between carp myosin and squid thin filament fraction. The results suggest that the regulatory system of the squid mantle muscle is actin-linked as in skeletal muscle rather than myosin-linked. This view is supported by the presence of troponin-like components on SDS-disc electrophoresis of squid thin filament fraction.
