kinesin

Kinesin is a type of molecular motor protein that operates inside cells to transport cargo, such as organelles and nutrients, along microtubules—tiny, tube-like structures. It functions like a microscopic train, using energy derived from ATP (a cellular fuel) to "walk" step-by-step along microtubules. This movement is essential for maintaining the cell's organization, distributing materials, and supporting various cellular processes. Kinesin's ability to efficiently move materials within cells is vital for health, growth, and overall cellular function.
