The mariner relic in the 3′ UTR of the sheep PrPtranscript. Translation of this sequence was guided by closely related mariner transposases of the Mellifera subfamily. Introduced frameshifts are indicated with a pound sign (#). The likely origin of stop codons is indicated. The terminal inverted repeats are indicated by arrows. The TG...TA flanking dinucleotides may be derived from the typical mariner TA target site. The orthologous human sequence is aligned with the flanking sites.
