Cryo-EM structures of actomyosin VI in multiple nucleotide states reveal a unique actin-myosin interface and a mechanism of force-sensitivity; furthermore, myosin VI remodels F-actin, suggesting a role for actin structural plasticity during force generation.

A cryptic pocket in the myosin motor domain selectively opens in molecular dynamics simulations, and the probability of pocket opening is predictive of how potently a compound will inhibit a particular myosin motor.

The structure of full-length myosin A provides some hints about its atypical mechanism, and reveals that the light chain PfELC is a target to block malaria pathogenesis.
Posterior determination of Drosophila oocyte is defined by competition between kinesin-1 removing posterior determinants from the cortex and myosin-V anchoring them.
