Myosin IIB kinetics refine contractility models; extends isoform biology but leaves open clinical translation in cardiomyopathy.
Rosenfeld et al. (2003) studied this question. Myosin IIB vs. Conventional myosin II counterparts was evaluated on Molecular features of myosin IIB. Myosin IIB exhibits unconventional features including a high duty ratio, rate-limiting ADP release, and high ADP affinity, distinguishing it from conventional myosin II counterparts.
