The four-residue segments that are almost identical in the two proteins. Concept introduction: NS1 protein is a non-essential (nonstructural protein) found in the influenza virus that is encoded by the viruses, yet not a part of the viral particle. They are mainly involved in the inhibitory actions against the host immune responses. H3 protein is one among the five histone proteins. It is a structural variant of the histone protein that is involved in packaging the DNA molecules into a structure called nucleosomes. There are some sequence similarities between the NS1protein of the influenza viruses and the H3 histone proteins.
