The addition of dynactin caused dynein to travel farther along the micro tubule.
<u>Explanation:</u>
Dynein is a family of cytoskeletal motor proteins that move along micro tubules in cells. They convert the chemical energy stored in ATP to mechanical work. Dynein transports various cellular cargo, provides forces and displacements important in mitosis, and drives the beat of eukaryotic cilia and flagella.
Dynactin is a 23 sub unit protein complex that acts as a co-factor for the micro tubule motor cytoplasmic dynein-1. It is built around a short filament of actin related protein-1.
