This circuitry involves an enzyme, GEF, that naturally circulates in a cell's cytoplasm. When this enzyme is activated, it induces a change in a protein, called Rho, that is known to be essential ...

A light-activated enzyme morphed round starfish egg cells into different shapes. This technology could one day be useful for ...

This shape change is driven by two enzymes: the small GTPase Rho and its activation enzyme GEF. By incorporating light-controllable molecular switches into GEF enzymes, the researchers managed to ...

Normally, these waves are triggered by proteins called Rho and enzymes known as GEF, which together activate muscle-like contractions in the cell’s outer layer. When GEF stimulates Rho ...

Researchers have discovered a key circuitry within a starfish oocyte that controls its motion and shape that involves the GEF enzyme that naturally circulates in a cell’s cytoplasm. When this ...
