How do motor proteins move
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). WebMotor proteins attach to vesicles and walk along a microtubule of the cytoskeleton. walk toward the microtubule organizing center (MTOC, or centrosome) and kinesins walk away …
