peptide

A bacterium that produces an insulin-like peptide can give mice type 1 diabetes, and infection with the microbe seems to predict the onset of the disease in humans, a study finds.

A peptide found in bull ant venom closely resembles a hormone of its primary predator, triggering hypersensitivity and making subsequent bites even more painful than the ones that came before.

Researchers link a stretch of DNA to a peptide of interest and measure current changes as the molecule is pulled by a helicase through a nanopore.

Researchers provide evidence that the Alzheimer’s-associated protein calibrates a signaling pathway that is conserved across the animal kingdom.

Membraneless organelles appear highly sensitive to ion concentrations in their environment.

Molecules similar to those produced by sea anemones are neuroprotective in a mouse cell model of Alzheimer’s disease.

Günter Blobel, known for his work on the signal hypothesis of protein targeting, has died from cancer at age 81.

The dust surrounding emerging, Sun-like stars contains methyl isocyanate, an organic molecule.

Researchers build a peptide that causes a receptor to form toxic, amyloid-like clumps in cells.

Four independent research groups develop techniques for visualizing peptide production in living cells.

Newly developed techniques from four different groups rely on the same basic steps to track translation in live cells.

A general guide to collecting and processing saliva

Researchers report an ability to detect several types of cancer in blood samples based on signatures of immune response, but some are skeptical about the utility of such a test.

The substance targets the same ion channel that's mutated in people who don't feel pain.

Candace Pert, who helped discover opioid receptors, has passed away at age 67.

Researchers show that peptides isolated from certain types of soybean inhibit the growth of human colon, liver, and lung cancer cells.
