Quick Summary

Dynein is an ATPase associated with microtubules that plays a crucial role in cellular movement. It is a motor protein that utilizes the energy from ATP hydrolysis to move along microtubules.12

This movement is essential for various cellular functions, including the transport of organelles and structures like cilia, flagella, and chromosomes. In cilia and flagella, dynein causes adjacent microtubules to slide past one another, generating the motion that propels cells or moves substances across cell surfaces. Dynein also acts as a transporter for membrane vesicles within cells, moving them along microtubules towards the minus end.12

…molecules of a protein called dynein that are attached along its length. Extensions of dynein, called dynein arms, connect neighbouring tubules, forming dynein cross-bridges. Dynein is involved in converting the chemical energy of adenosine triphosphate (ATP) into the mechanical energy that mediates flagellar movement. In the presence of ATP, dynein…
