Components of the TbNup76 complex, the trypanosome mRNA export platform. TbNup76 complex comprises of the β-propeller, coiled-coil protein, Nup76, the structural ortholog of Nup82/88 in yeast and vertebrates, respectively. TbNup76 forms a complex with two large FG-Nups with no obvious orthologs in opisthokonts. TbNup 149 appears to have a number of putative zinc fingers (Zn2+) on three repeats on the protein.
