Conformational Flexibility of p150Glued(1–191) Subunit of Dynactin Assembled with Microtubules

Microtubule (MT)-associated proteins perform diverse functions in cells. These functions are dependent on their interactions with MTs. Dynactin, a cofactor of dynein motor, assists the binding of dynein to various organelles and is crucial to the long-distance processivity of dynein-based complexes. The largest subunit of dynactin, the p150Glued, contains an N-terminus segment that is responsible for the MT-binding interactions and long-range...
