FIG. 1.
Structural organization of the regulatory region of JCVCY. NF-κB and ori, regulatory sequences for binding of the NF-κB transcription protein and the origin of viral DNA replication, respectively. The regulatory region of JCVCY contains one 98-bp repeat with two additional motifs of 23 and 66 bp. The 23-bp sequence element disrupts the pentanucleotide repeat sequence (AGGGAAGGGA). The nucleotide composition of the 23-bp insertion is shown at the bottom. The directions of transcription of the viral early and late promoters are indicated by the arrows.
