[[http://www.uniprot.org/uniprot/DYHC1_MOUSE DYHC1_MOUSE]] Cytoplasmic dynein 1 acts as a motor for the intracellular retrograde motility of vesicles and organelles along microtubules. Dynein has ATPase activity; the force-producing power stroke is thought to occur on release of ADP. [[http://www.uniprot.org/uniprot/TBB_PIG TBB_PIG]] Tubulin is the major constituent of microtubules. It binds two moles of GTP, one at an exchangeable site on the beta chain and one at a non-exchangeable site on the alpha chain. [[http://www.uniprot.org/uniprot/TBA1B_PIG TBA1B_PIG]] Tubulin is the major constituent of microtubules. It binds two moles of GTP, one at an exchangeable site on the beta chain and one at a non-exchangeable site on the alpha chain.

== Publication Abstract from PubMed ==

Dyneins are motor proteins responsible for transport in the cytoplasm and the beating of axonemes in cilia and flagella. They bind and release microtubules via a compact microtubule-binding domain (MTBD) at the end of a coiled-coil stalk. We address how cytoplasmic and axonemal dynein MTBDs bind microtubules at near atomic resolution. We decorated microtubules with MTBDs of cytoplasmic dynein-1 and axonemal dynein DNAH7 and determined their cryo-EM structures using helical Relion. The majority of the MTBD is rigid upon binding, with the transition to the high-affinity state controlled by the movement of a single helix at the MTBD interface. DNAH7 contains an 18-residue insertion, found in many axonemal dyneins, that contacts the adjacent protofilament. Unexpectedly, we observe that DNAH7, but not dynein-1, induces large distortions in the microtubule cross-sectional curvature. This raises the possibility that dynein coordination in axonemes is mediated via conformational changes in the microtubule.

Cryo-EM of dynein microtubule-binding domains shows how an axonemal dynein distorts the microtubule.,Lacey SE, He S, Scheres SH, Carter AP Elife. 2019 Jul 2;8. pii: 47145. doi: 10.7554/eLife.47145. PMID:31264960<ref>PMID:31264960</ref>
