Physicists from the Universities of Bayreuth and Grenoble have discovered a new mechanism of cell mobility. Their findings challenge the classical dogma that the molecular motor myosin is ...

Hair cells of the ear transduce sound via a mechanical link between hair bundle movement and channel gating, which is under tension at rest. A new paper reports that myosin-VIIa is critical for ...

Myosin-I is a biological motor that uses the chemical energy made by cells to ferry proteins within cells and to generate force, powering the movement of molecular cargos in nearly all cells.

Myosin-I is a biological motor that uses the chemical energy made by cells to ferry proteins within cells and to generate force, powering the movement of molecular cargos in nearly all cells.

Their results, published April 7 in Cell Reports, reveal that myosin-IIA generates cortex tension, while myosin-IIB maintains cortical stability.

The tool is designed to inactivate non-muscle myosin II, responsible for actomyosin contractility. To achieve this, the scientists used a protein called MYPT1 that inactivates myosin.

This tension supports the function of red blood cells by maintaining their shape and deformability. Adapted from "Myosin IIA interacts with the spectrin-actin membrane skeleton to control red ...
