Which motor protein typically moves cargo toward the 'minus' end of microtubules, usually toward the centrosome?
Show answer and explanation
Correct answer: Dynein
Cytoplasmic dyneins are minus-end directed motors that transport vesicles and organelles toward the cell center. Kinesins, conversely, are typically plus-end directed motors that move cargo toward the cell periphery.
