Members of this family of viral protein domains are implicated in transcriptional activation. They are almost completely alpha-helical, with five alpha-helices and a short, two-stranded, beta-ribbon. Four alpha helices (alpha1, alpha3, alpha4 and alpha5) are amphipathic and pack their hydrophobic surfaces around the central helix alpha2 [1].	Domain
