Fig. 1From: A purine-rich element in foamy virus pol regulates env splicing and gag/pol expressionScheme of the LTR-derived transcripts of PFV. The position of the C element is highlighted in blue. Exchanged nucleotides of the C element and SA3 sequences are underlined. The MaxEnt scores (ME) of SA2, SA3 and of the SA3 mutations C+ or Cn are depicted below the scheme. Arrows indicate positions of the LTR and the internal promoter. SA splice acceptor, SD splice donor, MSD major splice donorBack to article page
