Motor motion on cytoskeletal filaments is particularly important for biological length regulation, because numerous proteins targeted to microtubule ends modify their dynamics and can dramatically ...

Cytoplasmic dynein is the only microtubule minus end-directed motor in the cytoplasm of most eukaryotic cells and therefore carries out a huge range of functions, including organelle and mRNA ...

The motor domain contains the catalytic site for ATP hydrolysis and the actin or microtubule-binding site. The neck region acts as a lever arm, amplifying the small conformational changes generated by ...

Motor proteins (green dots) move along microtubules like trucks on a highway. Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases posted to EurekAlert! by ...
