kinesin is a type of motor protein found in cells that plays a crucial role in transporting cellular materials. It moves along microtubules, which are part of the cell's cytoskeleton, acting like tracks for the protein to travel on. Kinesin typically carries cargo such as organelles, proteins, and other essential molecules from one part of the cell to another, ensuring proper cellular function. Kinesin operates using energy derived from adenosine triphosphate (ATP), which it hydrolyzes to fuel its movement. This protein is essential for various cellular processes, including cell division and the maintenance of neuronal function, highlighting its importance in both health and disease.
