A map of where proteins are located in tissues and cells could help scientists understand the molecular basis of diseases such as cancer

In a finding that could speed the development of new protein-based drugs for fighting diabetes, hepatitis, and other diseases, researchers are reporting progress toward preventing or destroying an unusual structure that reduces the production yield of bioengineered drugs.

Even cells commute. To get from their birthplace to their work site, they sequentially attach to and detach from an elaborate track of exceptionally strong proteins known as the extracellular matrix.

Researchers have determined how an enzyme that stitches all-important molecular adjustments onto proteins contorts itself to regulate its own function

Iowa State University researcher Robert Jernigan believes that his research shows proteins have controlled motions.

A new bioinformatics tool is capable of identifying and correcting abnormal, incomplete and mispredicted protein annotations in public databases.

Researchers from the Virginia Bioinformatics Institute (VBI) at Virginia Tech have identified the region of a large family of virulence proteins in oomycete plant pathogens that enables the proteins to enter the cells of their hosts.

Extreme heat or cold is not only uncomfortable, it can be deadly-causing proteins to unravel and malfunction.

For male fruit flies, sperm is not enough in the battle to reproduce – at each mating a cocktail of proteins is transferred to the female, many of which directly influence female behaviours in ways that benefit the male. In a new paper, published in this week's PLoS Biology, the online open access journal, a team of biologists from Willie Swanson's lab have investigated these proteins using a new method that is able to identify male proteins in mated females.

Scientists at Harvard University and the University of Texas at Austin have found that genetic evolution is strongly shaped by genes' efforts to prevent or tolerate errors in protein production.

TexasA dynamic way to alter the shape and size of microscopic three-dimensional structures built out of proteins has been developed by biological chemist Jason Shear and his former graduate student Bryan Kaehr at The University of Texas at Austin.

Most of the functions performed by a cell are the result of interactions between proteins, which recognise their binding partner by affinity features localized on the protein surface.
