HTLV-1 provirus, mRNAs and proteins. HTLV-1 provirus is shown on top in blue with both LTRs painted in brown. Below, the transcripts and proteins encoded by a complete HTLV-1 provirus are shown. Sense transcripts are portrayed as black arrows with arrowheads pointing to the right, while antisense transcripts run in the opposite direction. Spliced exons are shown in solid black lines while introns are shown as dotted lines. Proteins derived from respective mRNAs are shown as empty squares
