Scientists discover how bacteria build protein signals in cells during infection

Posted by in category: biotech/medical

New research from Oregon Health & Science University could one day lead to therapies that prevent or treat diseases and infections tied to a protein that’s found in all human cells.

A study published today in the journal Molecular Cell describes how the protein ubiquitin is modified during bacterial infection.

The study details the steps taken to create a form of the protein known as lysine 6 polyubiquitin, where a long chain of ubiquitin molecules are linked through the amino acid lysine. This form of ubiquitin helps cells communicate by sending a molecular message—communication that remains poorly understood.
