These switches, which regulate protein functions, may prove to be a crucial factor in human ageing and the onset and treatment of diseases such as cancer, Alzheimer's disease and Parkinson's disease. The results of the team’s work have been published in the current edition of the journal Science.
"This is more than just a technological achievement, it has also expanded the number of known acetylation switches by a factor of six, and it gives us for the first time a comprehensive insight into this type of protein modification," says Professor Mann.
A given protein can perform more than one task, and how it behaves is regulated by adding a small molecule that acts as a 'switch' which can turn on the different tasks. Acetylation is essential for cells' ability to function normally. Defective protein regulation plays a role in ageing and the development of diseases such as cancer, Parkinson's and Alzheimer's.
"With the new mapping, we can now begin to study and describe how acetylation switches respond to medications that could repair the defects on them. It can have a major impact on medical care," says Professor Mann, adding that medications to repair the damaged protein regulation are already showing promising in the treatment of cancer.Cooperating proteins
The results of the team's research were published in the 17 July 2009 edition of Science.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
