Hypothesis-generating for myosin X motility; leaves open relevance to cardiovascular cell mechanics.
Ropars et al. (2016) studied this question. Myosin X vs. Single actin filaments was evaluated on Velocity and step size on actin bundles. A native myosin X dimer moves on actin bundles with higher velocities and takes larger steps than on single actin filaments.
