The binding of proteins to various substrates in a biological system is a basic but essential process to maintain the function of living things. The mechanisms underlying protein binding have been the focus of theoretical and experimental research for many years. Many mechanisms have been proposed and characterized, including "lock and key", "induced fit", "population shift" and "fly-casting". The recently discovered "fly-casting" mechanism allows a protein chain to unfold and extend to reach...

A protein's function depends on both the chains of molecules it is made of and the way those chains are folded. And while figuring out the former is relatively easy, the latter represents a huge challenge with serious implications because many diseases are the result of misfolded proteins. Now, a team of chemists at the University of Pennsylvania has devised a way to watch proteins fold in "real-time," which could lead to a better understanding of protein folding and misfolding in general....

Fifty years after the pioneering discovery that a protein's three-dimensional structure is determined solely by the sequence of its amino acids, an international team of researchers has taken a major step toward fulfilling a tantalizing promise: predicting the structure of a protein from its sequence alone. This advance could open a series of doors for previously intractable research into important biological processes and development of novel therapeutic drugs. The team from Harvard...

Fifty years after the pioneering discovery that a protein's three-dimensional structure is determined solely by the sequence of its amino acids, an international team of researchers has taken a major step toward fulfilling the tantalizing promise: predicting the structure of a protein from its DNA alone. The team at Harvard Medical School (HMS), Politecnico di Torino / Human Genetics Foundation Torino (HuGeF) and Memorial Sloan-Kettering Cancer Center in New York (MSKCC) has reported...

For more than a century, the use of X-rays has been a prime diagnostic tool when it comes to human health. As it turns out, X-rays also are a crucial component for studying and understanding molecules, and a new approach-just published by researchers at the University of Georgia-may dramatically improve what researchers can learn using the technique. One of the primary ways scientists can understand molecules is to bombard their crystalline forms with X-ray beams. This allows a...

Researchers at the RIKEN Brain Science Institute (BSI) have discovered a key mechanism responsible for selectively degrading aggregates of ubiquitinated proteins from the cell. Their findings indicate that the capture and removal of such aggregates is mediated by the phosphorylation of a protein called p62, opening the door to new avenues for treating neurodegenerative diseases such as Huntington's disease and Alzheimer's disease. One of the most important activities of a cell is the...
