Anyone who has ever tried to find a way through a crowded pedestrian zone has—literally—run into the problem: While some people choose to weave their way through the gaps, others stick to the straight and narrow, and ...

Filamentous polymers called microtubules play vital roles in chromosome segregation and molecular transport. An LMU team has now examined how microtubule lengths vary in response to changes in the availability of their protein ...

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 ...

To keep a cell alive, molecular motor proteins constantly transport building blocks and waste across the cell, along its biopolymer network. Because of the high density of these proteins, jamming effects are believed to affect ...

Motor proteins drive many of the essential processes in our cells. They move with a dancing motion, as Professor Erik Schäffer and his team have shown in a new study. In order to observe the tiny proteins, which are measured ...

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.

What bones are to bodies, the cytoskeleton is to cells. The cytoskeleton maintains cellular structure, builds appendages like flagella and, together with motor proteins, powers cellular movement, transport, and division. ...

University of Tokyo researchers have constructed the atomic model structure of the protein complex that corresponds to the stator (stationary part of a motor that surrounds the rotating part of a motor) of the E. coli flagellar ...

Living systems have the ability to produce collective molecular motions that have an effect at the macroscale, such as a muscle that contracts via the concerted action of protein motors. In order to reproduce this phenomenon, ...
