stathmin

Stathmin is a cellular protein that regulates microtubules, which are structural components inside cells essential for shape, transport, and division. By controlling microtubule stability, stathmin influences processes like cell growth, movement, and division. It works by binding to free tubulin—the building blocks of microtubules—and preventing them from assembling into larger structures. This action helps cells quickly reorganize their internal framework, especially during cell division and movement. Abnormal levels of stathmin are linked to cancer progression, as they can enable uncontrolled cell growth and metastasis.
