Kinesin is a motor protein that plays a crucial role in intracellular transport by carrying vesicles, organelles, or other cargo along microtubules. It moves by converting chemical energy from ATP into mechanical work, “walking” step-by-step along the microtubule’s filament. Each kinesin molecule has two globular heads that bind to the microtubule and hydrolyze ATP, allowing a coordinated hand-over-hand motion. This movement is directional, with kinesin typically traveling toward the plus end of the microtubule, ensuring efficient transport of materials to their intended locations within the cell. This process is vital for cellular organization, signaling, and function.
