What effect will addition of AMP-PNP have on axonal transport?

#Unit 2. Cellular Organization

  1. AMP-PNP induces tight binding of myosin (and most other microtubule motors) to microtubules; therefore, vesicle transport would cease because the motors would be locked onto the microtubules.

  2.  AMP-PNP induces tight binding of dynein (and most other microtubule motors) to microtubules; therefore, vesicle transport would cease because the motors would be locked onto the microtubules.

  3. AMP-PNP induces tight binding of kinesin (and most other microtubule motors) to microtubules; therefore, vesicle transport would cease because the motors would be locked onto the microtubules.

  4. AMP-PNP induces tight binding of myosin and kinesin (and most other microtubule motors) to microtubules; therefore, vesicle transport would cease because the motors would be locked onto the microtubules.
