Proteins and proteomics

Bacteriophage protein could make queso fresco safer
Researchers characterized the structure and function of PlyP100, a bacteriophage protein that shows promise as a food-safe antimicrobial for preventing Listeria monocytogenes growth in fresh cheeses.

Building the blueprint to block HIV
Wesley Sundquist will present his work on the HIV capsid and revolutionary drug, Lenacapavir, at the ASBMB Annual Meeting, March 7–10, in Maryland.

Gut microbes hijack cancer pathway in high-fat diets
Researchers at the Feinstein Institutes for Medical Research found that a high-fat diet increases ammonia-producing bacteria in the gut microbiome of mice, which in turn disrupts TGF-β signaling and promotes colorectal cancer.

Mapping fentanyl’s cellular footprint
Using a new imaging method, researchers at State University of New York at Buffalo traced fentanyl’s effects inside brain immune cells, revealing how the drug alters lipid droplets, pointing to new paths for addiction diagnostics.

Designing life’s building blocks with AI
Tanja Kortemme, a professor at the University of California, San Francisco, will discuss her research using computational biology to engineer proteins at the 2026 ASBMB Annual Meeting.

How lipid metabolism shapes sperm development
Researchers at Hokkaido University identify the enzyme behind a key lipid in sperm development. The findings reveal how seminolipids shape sperm formation and may inform future diagnostics and treatments for male infertility.

Mass spec method captures proteins in native membranes
Yale scientists developed a mass spec protocol that keeps proteins in their native environment, detects intact protein complexes and tracks drug binding, offering a clearer view of membrane biology.

Laser-assisted cryoEM method preserves protein structure
University of Wisconsin–Madison researchers devised a method that prevents protein compaction during cryoEM prep, restoring natural structure for mass spec studies. The approach could expand high-resolution imaging to more complex protein systems.

Method sharpens proteome-wide view of structural changes
Researchers developed a method that improves limited proteolysis coupled with mass spectrometry, separating true changes from abundance or splicing effects.
