FIG 4.

Mapping the tetherin gene to the P. alecto genome. (A) Tetherin gene location (dark blue) and neighboring genes (purple). Arrows indicate the orientation of each gene’s protein coding domain sequence. Sequence numbers and gene orientations are relative to the beginning of the gene scaffold in the 5′ to 3′ direction. (B) Tetherin mRNA exons are shown and color-coded: isoform A, red; isoform B, blue; isoform C, green. Exons are mapped to scale against the tetherin gene. Sequence numbers are relative to the beginning of the gene. The 5′ and 3′ untranslated regions of the mRNA are colored black.
