Calcium gets myosin VI ready for work.

The myosins are a large family of actin-binding motor proteins that convert stored chemical energy into work, with important functions in intracellular transport, force generation, and mechanosensation (1). Despite many advances in understanding the mechanical and kinetic properties of purified myosins in vitro, the signals that regulate the functions of these molecular motors in cells are not ...

In each case, one strategy for making sure a protein gets where it belongs is to shuttle its messenger R...
