Fig. 4From: Novel transcription regulatory sequences and factors of the immune evasion protein ICP47 (US12) of herpes simplex virusesa. The US12 TRSs and TRFs are conserved among HSV-1 strains. Red lines indicate the conserved regions 1–14. The TRSs and TRFs are shown in colored boxes. b The US12 TRSs and TRFs are identical among HSV-2 strains. Red lines indicate the conserved regions 1–17. The TRSs and TRFs are shown in colored boxesBack to article page
