CC -!- FUNCTION: Stimulator of protein export for NES-containing proteins
CC (PubMed:10567585). Also plays a role in the nuclear export of U1 snRNA,
CC tRNA, and mRNA (PubMed:10848583). The NXF1-NXT1 heterodimer is involved
CC in the export of HSP70 mRNA in conjunction with ALYREF/THOC4 and THOC5
CC (PubMed:19165146, PubMed:11259602). {ECO:0000269|PubMed:10567585,
CC ECO:0000269|PubMed:10848583, ECO:0000269|PubMed:11259602,
CC ECO:0000269|PubMed:19165146}.
CC -!- SUBUNIT: Heterodimer with NXF1 (PubMed:11583626). Forms a complex with
CC RANGAP1, RANBP2/NUP358 and NXF1 (PubMed:14729961). Interacts (via NTF2
CC domain) with NXF1 (PubMed:11583626). Stabilizes the NTF2 domain of NXF1
CC by heterodimerization (PubMed:11583626). The formation of NXF1-NXT1
CC heterodimers is required for the NXF1-mediated nuclear mRNA export
CC (PubMed:11583626). Preferentially binds Ran-GTP (PubMed:10567585).
CC Associates with NXF2, NXF3 and NXF5. Does not bind nucleoporins (NPC)
CC directly, its association to NPC is mediated by NXF1 (PubMed:11583626).
