WebSep 3, 2013 · Although dynein is known to carry certain cargoes through regions outside its motor domain, how it transports other microtubules is not well understood. ... Inside the overlap, dynein often pauses and switches directions, suggesting the motor spends a fraction of time stepping with both motor domains on a single MT in the overlap, and … WebApr 8, 2016 · Dyneins are a large family of motor proteins that harness the energy of ATP-hydrolysis to move along microtubules in the minus end direction. There is one cytoplasmic dynein-1, one cytoplasmic-dynein-2 and a large family of axonemal dynein isoforms. 1 Among these different isoforms, dynein-1 is responsible for most of the microtubule … sharps login
