WebWhen motor proteins drag organelles to move, the motion also creates a current surrounding the cytosol. If many motor proteins move along one direction (for example, … 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). ireland red hairMotor proteins utilizing the cytoskeleton for movement fall into two categories based on their substrate: microfilaments or microtubules. Actin motors such as myosin move along microfilaments through interaction with actin, and microtubule motors such as dynein and kinesin move along microtubules … See more Motor proteins are a class of molecular motors that can move along the cytoplasm of cells.
