Researchers at the University of Tsukuba have reported on the structure and light energy transfer efficiency of a protein ...

E1s and E2s first work generically across the cell to activate and prepare ubiquitin for attachment. E3 ligases then ensure that the tag is added to the right protein; as such, hundreds of specific ...

RNA splicing is a cellular process that is critical for gene expression. After genes are copied from DNA into messenger RNA, portions of the RNA that don't code for proteins, called introns, are cut ...

Scientists have now mapped the forces acting inside a proton, showing in unprecedented detail how quarks—the tiny particles ...

BYU Professor David Thomson is working to understand a chemical pathway in human muscles that may explain the effects of exercise.
