How protein complexes form in the cell

The formation of protein complexes is a highly organised process that does not begin with the "finished" proteins. Studies conducted by researchers at the Center for Molecular Biology of Heidelberg University (ZMBH) and the ...

Misfolded proteins serve as 'inherited memory' of toxic insults

Protein aggregates have a bad reputation in conditions such as Alzheimer's disease and Parkinson's disease, but in bacteria, inheritance of aggregates by daughter cells may help protect against the same toxic stresses that ...
