The role of microtubules in DDA assembly has been elusive. Here, we reveal detailed structural insights into microtubule-mediated DDA assembly using cryo-electron microscopy. We find that an adaptor-independent dynein-dynactin complex (DD) predominantly forms on microtubules in an intrinsic 2:1 stoichiometry, induced by spontaneous parallelization of dynein upon microtubule binding. Adaptors can squeeze in and exchange within the assembled microtubule-bound DD complex, which is enabled by relative rotations between dynein and dynactin, and further facilitated by dynein light intermediate chains that assist in an adaptor 'search' mechanism. Our findings elucidate the dynamic adaptability of the dynein transport machinery, and reveal a new mode for assembly of the motile complex. | |||||||||
