Kinesin is a type of protein that plays a crucial role in the transportation of cellular cargo, such as organelles, vesicles, and protein complexes, along microtubules in eukaryotic cells. Microtubules are filamentous structures that form part of the cytoskeleton of cells and are involved in many cellular processes, including cell division and intracellular transport. Kinesins are motor proteins that use energy from the hydrolysis of ATP to move along microtubules in a process called “walking.” They have a characteristic two-headed structure, with one end of the protein attached to the cargo being transported, and the other end attached to the microtubule. There are many different types of kinesins, each with different functions and characteristics. For example, some kinesins move towards the plus end of the microtubule, while others move towards the minus end. Kinesins are involved in a wide variety of cellular processes, including mitosis, neuronal transport, and intracellular trafficking, and they are the subject of intense research in cell biology and biotechnology.
