For cancer cells to grow and spread around the human body, they need proteins that bind copper ions. New research about how cancer-related proteins bind the metal and how they interact with other ...

Protein cages found in nature within microbes help weather its contents from the harsh intracellular environment -- an observation with many bioengineering applications. Researchers recently developed ...

Iowa State University researchers have described with single-molecule precision how copper ions cause prion proteins to misfold and seed the misfolding and clumping of nearby prion proteins. The ...

In biology, proteins don’t go it alone. They fold up in complexes and interact with each other to get stuff done. Those interactions create challenges for scientists working to predict protein ...

Which structures do complex proteins adopt in solution? Biophysicists answer this question using the example of ubiquitin dimers as well as a new combination of high-resolution NMR spectroscopy and ...
