Final answer:
Minus end-directed motor proteins like dynein are typically involved in retrograde movement in axons, but can also contribute to anterograde transport through interactions with different adaptors or microtubule tracks, indicating their versatility in intracellular transport.
Step-by-step explanation:
The same minus end-directed motor protein, such as dynein, can participate in both anterograde and retrograde movement within axons by changing the cargo adaptor or the microtubule tracks it interacts with. This adaptability allows dynein to transport different cargoes in opposite directions. In anterograde transport, motor proteins like kinesin carry vesicles towards the axon terminal, whereas dynein, usually involved in retrograde transport, can also contribute to anterograde movements under certain conditions, such as changes in the microtubule network or in association with other proteins that alter its directionality.
This dual capability is essential for the proper functioning of neuronal cells which require a dynamic and regulated system of transport for neurotransmitters and other cellular components.
