In molecular biology the CVNH domain (CyanoVirin-N Homology domain) is a conserved protein domain. It is found in the sugar-binding antiviral protein cyanovirin-N (CVN) as well as proteins from filamentous ascomycetes and in the fern Ceratopteris richardii.Cyanovirin-N (CV-N) is an 11-kDa protein from the cyanobacterium Nostoc ellipsosporum that displays virucidal activity against several viruses including human immunodeficiency virus (AIDS).
