Kinesin is a protein belonging to a class of motor proteins found in eukaryotic cells. Kinesins move along microtubule filaments, and are powered by the hydrolysis of ATP (thus kinesins are ATPases). The active movement of kinesins supports several cellular functions including mitosis, meiosis and transport of cellular cargo. Most kinesins walk towards the plus end of a microtubule, entails transporting cargo from the centre of the cell towards the periphery. Kinesins were discovered as microtubule (MT)-based anterograde intracellular transport motors. The founding member of this superfamily, the genomes of mammals encode more than 40 kinesin proteins, organized into at least 14 families named kinesin-1 through kinesin-14.
