Actin is a highly abundant protein that controls the shape and movement of all our cells. Actin achieves this by assembling into filaments, one actin molecule at a time. The proteins of the formin ...

Actin filaments were found to be present in phragmoplasts about 35 years ago, and a lot of research has been done since then, but there appears to be no report on this phenomenon," said Dr. Higaki.

The Osaka team demonstrated how, in the absence of calcium ions, myosin access to the actin regions are blocked so that myosin heads cannot attach to them for muscle contraction.

A disturbance in this balance leads to several diseases, such as invasive cancers. The most important component of both protrusive and contractile machineries is a protein called actin.
