Motor proteins fulfill the role of transporting large cargo about the cell to their required destinations. Kinesins are motor proteins that transport such cargo by walking unidirectionally along microtubule tracks hydrolysing one molecule of adenosine triphosphate (ATP) at each step. See more A kinesin is a protein belonging to a class of motor proteins found in eukaryotic cells. Kinesins move along microtubule (MT) filaments and are powered by the hydrolysis of adenosine triphosphate (ATP) (thus kinesins are See more Kinesins were discovered in 1985, based on their motility in cytoplasm extruded from the giant axon of the squid. They turned out as … See more In the cell, small molecules, such as gases and glucose, diffuse to where they are needed. Large molecules synthesised in the cell body, … See more In 2024 direct visualization of kinesin "walking" along a microtubule, in real-time was reported. In a "hand-over-hand" mechanism, the … See more Overall structure Members of the kinesin superfamily vary in shape but the prototypical kinesin-1 motor consists of two Kinesin Heavy Chain (KHC) molecules which form a protein dimer (molecule pair) that binds two light chains … See more Motor proteins travel in a specific direction along a microtubule. Microtubules are polar; meaning, the heads only bind to the microtubule in one orientation, while ATP binding gives each … See more A number of theoretical models of the molecular motor protein kinesin have been proposed. Many challenges are encountered in theoretical investigations given the remaining … See more The wide variety of myosin genes found throughout the eukaryotic phyla were named according to different schemes as they were discovered. The nomenclature can therefore be somewhat confusing when attempting to compare the functions of myosin proteins within and between organisms.
