>cd01371 KISc_KIF3 Kinesin motor domain, kinesins II or KIF3_like proteins. Subgroup of kinesins, which form heterotrimers composed of 2 kinesins and one non-motor accessory subunit. Kinesins II play important roles in ciliary transport, and have been implicated in neuronal transport, melanosome transport, the secretory pathway, and mitosis. This catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. Kinesins are microtubule-dependent molecular motors that play important roles in intracellular transport and in cell division. In this group the motor domain is found at the N-terminus (N-type). N-type kinesins are (+) end-directed motors, i.e. they transport cargo towards the (+) end of the microtubule. Kinesin motor domains hydrolyze ATP at a rate of about 80 per second, and move along the microtubule at a speed of about 6400 Angstroms per second. To achieve that, kinesin head groups work in pairs. Upon replacing ADP with ATP, a kinesin motor domain
