Microtubules Discovered to Play an Active Role in Correctly Distributing Chromosomes During Cell Division

Newswise — 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 geometry of the enzyme’s substrate proteins attached to them and controlling when key events …

Microtubules Found to Actively Ensure Accurate Chromosome Distribution

For decades, microtubules, slender dynamic filaments integral to a cell’s cytoskeleton, were regarded predominantly as passive structural elements, serving as mere mechanical scaffolds that maintain cellular shape and provide tracks for intracellular transport. However, a groundbreaking study published in Science Advances has radically transformed this perspective, uncovering a vital, previously unappreciated signaling capacity of microtubules. …
