Fig. 1.

RNA sequence of the HPV16 LRE at the junction of the L1 open reading frame and the long control region (LCR). The L1 UAA stop codon is in bold type. The four weak 5′ splice sites (Cumming et al., 2003) are underlined and the 3′ GU-rich region is in italic type. A putative hnRNP A1 binding site is boxed. Truncated LRE probes used in experiments described in Fig. 5 are indicated beneath the sequence.
