Cooperation in Heat Shock Protein Observed Using Foerster Resonance Energy Transfer Methodology

As in a successful football match, all actors in a cell must play in perfect coordination. A typical example for this kind of cooperation can be seen in the heat shock protein Hsp90, which controls the proper folding of other proteins. Together with a second molecule, the co-chaperone P23, it splits the energy source ATP to release the energy it needs to do its work.

Arrangement of Cell Membrane Molecules Determined Using Nanoscale Tape Measure

The surface of a cell plays a central role in its communication. Up to now, it was questioned whether its molecules arise in an ordered way on the nanoscale and whether this implies specific functions. Thanks to a new technique, researchers from the University of Freiburg and Max Planck Institute of Immunobiology and Epigenetics were able to detect surface structures and their changes far below the resolution limit of light.

Protein Function Like a Nanoscale ‘Velcro’

Biological membranes are like a guarded border. They separate the cell from the environment and at the same time control the import and export of molecules. The nuclear membrane can be crossed via many tiny pores.

Clusters of Ras Proteins Linked to Cancer Warp Cell Membranes

Supercomputer simulations have shown that clusters of a protein linked to cancer warp cell membranes, according to scientists at The University of Texas Health Science Center at Houston (UTHealth) Medical School. This research on these protein clusters, or aggregates as scientists call them, could help guide design of new anticancer drugs.
