Microtubules, the dynamic filaments that form the cell's internal scaffolding, have long been viewed as mere passive structural supports. But a new study reveals they play a far more active signaling role. The findings, published in Science Advances, demonstrate that microtubules are in fact regulators of enzymatic reactions through reshaping the geometry of the enzyme's substrate proteins attached to them and controlling when key events occur to conduct cell division.
