A new way to discover structures of membrane proteins

University of Toronto scientists have discovered a better way to extract proteins from the membranes that encase them, making it easier to study how cells communicate with each other to create human health and disease.

3-D mapping a new drug-delivery tool

Cubosomes are small biological 'capsules' that can deliver molecules of nutrients or drugs with high efficiency. They have a highly symmetrical interior made of tiny cubes of assembled fat molecules similar to the ones in ...

Membrane enzymes 'stop and frisk' proteins indiscriminately

For what is believed to be the first time, researchers at The Johns Hopkins University have illuminated the inner workings of an important class of enzymes located inside the outer envelopes of cells. Much to their surprise, ...

Dynamic systems in living cells break the rules

There is considerable interest in understanding transport and information pathways in living cells. It is crucial for both the transport of, for example, medicine into cells, the regulation of cell life processes and their ...
