Researchers found that paired pathogenic variants can restore protein function rather than make it worse. This phenomenon ...

Despite vaccines and treatments, SARS-CoV-2—the virus that causes COVID-19—continues to pose a global health threat, driven by new variants and its ability to hijack human cells in ways that still ...

Proteins are the molecular machines of cells. They are produced in protein factories called ribosomes based on their ...

Scientists have uncovered a direct molecular mechanism by which gut bacteria inject proteins into human cells, reshaping immune responses and potentially driving inflammatory disease. Scientists have ...

Researchers have elucidated key steps in the ubiquitin tagging of the mutated huntingtin protein, providing hope for future ...

Most mutations that cause disease by swapping one amino acid out for another do so by making the protein less stable, according to a major study of human protein variants that was published in Nature ...

Researchers have uncovered a microscopic weapon that can literally tear viruses apart from the inside, a single protein that ...

New research by UCLA Health and UC San Francisco has uncovered why certain brain cells are more resilient than others to the buildup of a toxic protein that is a hallmark of Alzheimer's disease and ...

The recommended target for protein intake increased from 0.8 g/kg/day to 1.2-1.6 g/kg/day in 2026. Individual protein requirements vary by age, sex, and physical activity.
