New technique tracks individual protein movement on live cells

The piece of gold that Richard Taylor was thrilled to track down weighed less than a single bacterium. Taylor, a postdoctoral fellow at the Max Planck Institute, was working to follow individual nanogold-labeled molecules ...

Molecular motors direct the fate of stem cells

Scientists at the University of Groningen and the University Medical Center Groningen used molecular motors to manipulate the protein matrix on which bone marrow-derived mesenchymal stem cells are grown. Rotating motors altered ...

Study reveals dynamics of crucial immune system proteins

Of the many marvels of the human immune system, the processing of antigens by the class I proteins of the major histocompatability complex (MHC-I) is among the most mind-boggling. Exactly how these proteins carry out their ...

Surface protein editing in bacteria

University of Minnesota researchers have discovered this previously unknown signaling pathway that regulates surface proteins on bacteria that can lead to new targets for antibiotics.

The exocyst dynamo

The exocyst is a protein complex essential for life, that is comprised of eight subunits and is a crucial component in vesicle trafficking.

Putting a face on a cell surface

On the cell surface, anchored in the cell membrane, a wide array of proteins perform functions, which are vital for the cell. These proteins, collectively known as the surfaceome, are a cell's antennae to the outside world, ...
