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 ...

These new findings shed light on the role of myosin I in cells, supporting the notion that this molecular motor is more important in generating and sustaining tension rather than transporting ...

that controls the activity of Myosin, a motor protein essential for generating and maintaining cellular tension. Cells as rubber bands To prove their hypothesis, the researchers used a technique ...

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. Maintenance of cortical stability by myosin-IIB ...

MYPT1 brings the phosphatase, PP1c, close to myosin resulting in myosin ... blue light locally at both poles of a dividing cell weakened the tension in the cell’s cortex, increasing the ...

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 ...
