WebThey found the movement rates of motor protein can be tuned by genetically exchanging its “feet”. For example, using the “feet” from Chara alga can generate a high-speed motor protein (moves in 16 µm/sec), and using the human cell’s “feet” will result in a low-speed version (0.2 µm/sec). WebJan 2, 2024 · Motor proteins, such as myosins and kinesins, move along cytoskeletal filaments via a force-dependent mechanism that is driven by the hydrolysis of ATP molecules (reviewed in [1] ). Which is the most commonly described motor protein? The most commonly described motor proteins belong to the Myosin superfamily.
