Regulation of actin-myosin interaction.

P Dancker.   

Abstract

In the presence of the regulatory protein complex tropomyosin-troponin ATPase activity of vertebrate skeletal muscle actomyosin is either higher or lower than in the absence of tropomyosin-troponin. The actual behavior depends on ionic strength, Ca2+ concentration, ATP concentration (determining the amount of rigor complexes present), and the ratio between actin and myosin. This effect of the myosin-actin ratio implies that under certain conditions cooperativity in actin-myosin interaction can be seen.
