While scientists still don’t fully understand the diverse nature of RNA molecules, it is believed that the proteins binding to them, called RNA-binding proteins, are associated with many disease formation. A research led by biomedical scientists from City University of Hong Kong (CityU) has developed a novel detection method, called CARPID, to identify binding proteins of specific RNAs in the living cells. It is expected the innovation can be applied in various cell research, from identifying biomarkers of cancer diagnosis to detecting potential drug targets for treating viral diseases.
