The propensity of proteins to stick together in large clumps—termed "protein aggregation"—is the culprit behind a variety of conditions including Huntington's, Alzheimer's, and mad cow diseases. With this notoriety, protein aggregation is considered to be a bad accident of nature that happens when protein structure is mismanaged. But new research published online on June 13th in the Cell Press journal Developmental Cell shows that, when kept in balance, protein aggregation has beneficial functions that allow cells to organize themselves in both time and space. The findings will be valuable as researchers design treatments for diseases that involve this process.
