title: Molecular cloning of the viperin gene and its promoter region from the mandarin fish Siniperca chuatsi.
abstract: A viperin gene has been cloned from the mandarin fish (Siniperca chuatsi). From the first transcription initiation site, the mandarin fish viperin gene extends 3163 nucleotides to the end of the 3' untranslated region, and it contains six exons and five introns. The open reading frame of the viperin transcript has 1062 nucleotides which encode a 354 amino acid peptide. The amino acid sequence of mandarin fish viperin shows high identities with its homologues in teleosts and mammals except for the first 70 amino acids. A characteristic feature in the viperin promoter region was the presence of five putative ICSBP (IRF8) binding sites and one IRF1 binding site. The viperin gene expressed mainly in lymphoid tissues before stimulation, but its expression can be examined in almost all the organs investigated after stimulation with virus or Poly I:C. The expression pattern and promoter sequence may be considered as the indirect evidence that the transcription of viperin is regulated by interferons or interferon induced genes.
