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 ...

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 ...

Microtubules are protein fibers that facilitate the transport of cellular components throughout a cell’s interior. Within a cell, microtubules span from the nucleus to the cell membrane, and the motor ...

Motor proteins that pause at the ends of microtubules and produce pushing forces can also stimulate their growth, according to researchers at Penn State. The proteins' function could be a critical ...

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 ...
