Unconventional functions of microtubule motors

► Microtubule motors have numerous functions that are not related to their main function in cargo transport. ► Some functions of microtubule motors do not require their motor activity. ► Microtubule motors modulate interactions between signaling proteins, including transcription factors. ► Microtubule motors facilitate phosphorylation by recruiting kinases to their substrates. ► Microtubule motors generate movement of cellular constituents by a variety of unconventional mechanisms.
