How a tiny chemical tag called sulfotyrosine affects infections and blood clotting

Sulfotyrosine, an essential determinant for diverse protein-protein interactions

NIH-funded research University of California at Davis · NIH-11260151

Researchers are looking at how a small chemical change called sulfotyrosine changes how viruses like HIV enter cells and how molecules that affect blood clotting work, to help people with infections or clotting problems.

What this research studies

This project focuses on a chemical tag on proteins called sulfotyrosine that can change how proteins stick together and signal. The team will find and map receptors that bind sulfated peptides, analyze the molecular interfaces where binding happens, and develop ways to produce and test new sulfated molecules. Work will combine biochemical experiments, structural analysis, and cell-based assays relevant to viral entry and clotting biology. Findings aim to connect basic molecular details to potential therapeutic molecules.

Who could benefit from this research

Good fit: People living with HIV or those with blood-clotting disorders would be the most likely future beneficiaries or candidates for downstream trials based on this research.

Not a fit: Patients without infectious diseases or clotting issues are unlikely to see direct benefit from this laboratory-focused work in the near term.

Why it matters

Potential benefit: If successful, the work could point to new ways to block HIV entry or to design sulfated peptides that treat blood-clotting problems.

How similar studies have performed: Prior studies have shown sulfotyrosine plays a key role in HIV entry and that some sulfated peptides can affect clotting, so this builds on promising but still incomplete early findings.
