Within both plant and animal cells, motor proteins act like the engines in a busy train system. They shuttle material in the cell from one location to another. And just as commuter trains travel a predictable route in a defined ...

Microtubules are roads made of proteins that extend throughout a cell for motor proteins (carriers) to deliver neuronal cargo packed with many kinds of materials required for cellular activity. The delivery is active along ...

It is one of the great mysteries in biology: How does a cell neatly distribute its replicated DNA between two daughter cells? For more than a century, we have known that DNA in the cell is comparable to a plate of spaghetti—a ...

According to a theoretical model developed by LMU physicists, in cell protrusions, cargo-transporting motor proteins often get in each other's way. The upshot is that freely diffusing proteins reach the leading edge faster.
