Researchers have discovered a human protein that helps in fighting the Ebola virus. In the study the team from Northwestern University used mass spectrometry -- a technique that identifies specific elements in a sample by mass -- to search for interactions between human proteins and Ebola virus proteins. They found strong evidence for an interaction between the Ebola virus protein VP30 and the human protein RBBP6 Xinhua news agency reported on Thursday. The results were published in the journal Cell. Further structural and computational analysis narrowed the interaction down to a small 23-amino acid-long peptide chain. This small group of
