[https://www.uniprot.org/uniprot/NXT1_HUMAN NXT1_HUMAN] Stimulator of protein export for NES-containing proteins. Also plays a role in the nuclear export of U1 snRNA, tRNA, and mRNA. The NXF1-NXT1 heterodimer is involved in the export of HSP70 mRNA in conjunction with ALYREF/THOC4 and THOC5.<ref>PMID:10567585</ref> <ref>PMID:10848583</ref> <ref>PMID:11259602</ref> <ref>PMID:19165146</ref>

TAP-p15 heterodimers have been implicated in the export of mRNAs through nuclear pore complexes (NPCs). We report a structural analysis of the interaction domains of TAP and p15 in a ternary complex with a Phe-Gly (FG) repeat of an NPC component. The TAP-p15 heterodimer is structurally similar to the homodimeric transport factor NTF2, but unlike NTF2, it is incompatible with either homodimerization or Ran binding. The NTF2-like heterodimer functions as a single structural unit in recognizing an FG repeat at a hydrophobic pocket present only on TAP and not on p15. This FG binding site interacts synergistically with a second site at the C terminus of TAP to mediate mRNA transport through the pore. In general, our findings suggest that FG repeats bind with a similar conformation to different classes of transport factors.
