Cell: Protein folding via charge zippers

Membrane proteins are the "molecular machines" in biological cell envelopes. They control diverse processes, such as the transport of molecules across the lipid membrane, signal transduction, and photosynthesis. Their shape, ...

Individual cells respond to electrical signal

Researchers at the Department of Molecular Nanofabrication (part of the University of Twente's MESA+ Institute for Nanotechnology) have published their preliminary results in a prominent article in Angewandte Chemie. This ...

Jigsaw a critical piece of the Notch puzzle

The Notch signaling pathway helps determine cell fate determination, differentiation and proliferative ability of numerous cells. How it accomplishes these tasks has been a puzzle, but researchers led by those at Baylor College ...

Unusual protein helps regulate key cell communication pathway

Charged atoms, or ions, move through tiny pores, or channels, embedded in cell membranes, generating the electrical signals that allow cells to communicate with one another. In new research, scientists have shown how an unusual ...

New technique enables study of 'challenging' proteins

Researchers from Hull, Bristol and Frankfurt have shown that a new technique for identifying molecular structure can be used effectively on small samples of biological proteins, particularly proteins that are targeted for ...

Protein love triangle key to crowning bees queens?

A honey bee becomes a royal queen or a common worker as a result of the food she receives as a larva. While it has been well established that royal jelly is the diet that makes bees queens, the molecular path from food to ...

Chemists reveal the force within you

A new method for visualizing mechanical forces on the surface of a cell, reported in Nature Methods, provides the first detailed view of those forces, as they occur in real-time.
