The motion of motor proteins on biopolymers is important for diverse biological processes. Actin, microtubules, and nucleic acids can serve as one-dimensional tracks on which motor proteins move.

ATP hydrolysis causes a conformational change in these proteins' globular motor domains, allowing them to "walk" along their associated filaments (see Feature, p. 19). These superfamilies contain ...

Cytoplasmic dynein is a vital microtubule-based motor protein that drives retrograde intracellular transport, supporting essential cellular functions ranging from organelle positioning to cell ...

For decades, scientists have known that motor proteins like kinesin-2 ferry vital cargo along microtubule "highways" inside cells. But how these molecular vehicles identify and bind to the right cargo ...

How well bacteria move and sense their environment directly affects their success in surviving and spreading. About half of known bacteria species use a flagella to move — a rotating appendage that ...

Most of us will probably be able to recall at least vaguely that a molecule called ATP is essential for making our bodies move, but this molecule is only a small part of a much larger system. Although ...

DNA-nanoparticle motors are exactly as they sound: tiny artificial motors that use the structures of DNA and RNA to propel motion by enzymatic RNA degradation. Essentially, chemical energy is ...

The kinesin-2 motor protein uses a hook-like adaptor and cargo-binding (HAC) domain to recognize and transport cargo along microtubule highways, revealing a cellular logistics system critical for ...
