FIGURE 4.

Alternative splicing of NUP116/NUP100 orthologs in the Saccharomycotina. (A) Splicing pattern is shown for each of the species analyzed, along with the species phylogeny as in Figure 1A. (B) C. jadinii diverged before the likely origin of NUP116/NUP100 alternative splicing and its ortholog lacks an intron. The C. jadinii ortholog contains a sequence that is homologous to the sequence in Nup116 that binds to Gle2. (C) Intron retention in the NUP116/NUP100 ortholog of L. kluyveri. (D) Intron retention in the NUP116/NUP100 ortholog of T. delbrueckii. (E,F) Duplicated NUP116 and NUP100 genes in S. cerevisiae lack introns and only Nup116 contains the Gle2 binding site.
