Most of the attention directed at в-amyloid precursor protein (APP) has focused on its cleavage and its cleavage products, such as Aв, one of the hallmarks of Alzheimer’s disease. However, there are clues that full-length APP has important developmental roles.

A group of signaling proteins known as Wnt - which help build the human body’s skin, bone, muscle and other tissues - depend on a complex delivery and recycling system to ensure their transport to tissue-building cell sites, according to a study at Cincinnati Children’s Hospital Medical Center.

The Stowers Institute’s Rong Li Lab, in collaboration with the Institute’s Imaging Center, has achieved a quantitative in vivo measurement of the dynamic protein-protein interactions in the mitogen-activated protein (MAP) kinase cascade signaling pathway, which is critical to growth and differentiation decisions in all eukaryotic cells.

Researchers from Johns Hopkins and the University of Pennsylvania have uncovered another reason why one of the most commonly activated proteins in cancer is in fact so dangerous.

Cells in our body come in various shapes and sizes. Each cell is shaped in such a way as to optimise it for a specific function. When things go wrong and a cell does not adopt its dedicated shape, its function can be impaired and the cell can cause problems in the body.

When you meet your boss's husband, Harvey, at the office holiday party, then bump into him an hour later over the onion dip, will you remember his name?

A protein in mice known as RGS13 suppresses allergic reactions, including the severe, life-threatening allergic reaction known as anaphylaxis, according to scientists at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH).

The syrupy soup of proteins, ribosomes and membranes inside a living cell is so tightly packed it may increase the structural content of proteins by as much as 25 percent, according to new research from Rice University and the University of Houston (UH).

For the first time, researchers have linked increased friction with early wear in the joints of animals. Work led by Brown University physician and engineer Gregory Jay, M.D., shows mice that do not produce the protein lubricin begin to show wear in their joints less than two weeks after birth. This finding not only points up the protective power of lubricin but also suggests that it could be used to prevent joint wear after an injury.

Researchers at the BSC and the IRB Barcelona unveil crucial information about the protein transporter of oxygen, which opens up the possibility to optimize its function by introducing modifications. The study is published in the scientific journal Proceedings of the National Academy of Sciences.

Researchers at MIT studying the architecture of proteins have finally explained why computer models of proteins’ behavior under mechanical duress differ dramatically from experimental observations. This work could have vast implications in bioengineering and medical research by advancing our understanding of the relationship between structure and function in these basic building blocks of life.

Ubiquitin is a small protein, which can be attached to other cellular proteins, a process known as ubiquitination. Discoveries in the 1980 th on a key function of ubiquitination in the regulation of protein degradation where awarded with the Nobel Prize for chemistry in 2004.
