Findings in desensitized actomyosin systems warrant no clinical changes; leaves open tropomyosin's role in cation selectivity for intact muscle regulation.
The study demonstrates that the interaction of myosin with actin, tropomyosin, and troponin alters its ATPase activity specificity for bivalent cations, primarily based on metal ion size, highlighting the unique Ca2+ sensitivity of the Mg2+-stimulated natural actomyosin system.
Schaub et al. (1969) studied this question.
