Human Gene NXT1 (uc002wsx.1) Description and Page Index
  Description: Homo sapiens NTF2-like export factor 1 (NXT1), mRNA.
RefSeq Summary (NM_013248): The protein encoded by this gene is located in the nuclear envelope. It has protein similarity to nuclear transport factor 2. This protein functions as a nuclear export factor in both RAN (Ras-related nuclear protein)- and CRM1 (required for chromosome region maintenance)-dependent pathways. It is found to stimulate the export of U1 snRNA in RAN- and CRM1-dependent pathways and the export of tRNA and mRNA in a CRM1-independent pathway. The encoded protein heterodimerizes with Tap protein and may regulate the ability of Tap protein to mediate nuclear mRNA export. The use of alternate polyadenylation sites has been found for this gene. [provided by RefSeq, Jul 2008].

-  Comments and Description Text from UniProtKB
DESCRIPTION: RecName: Full=NTF2-related export protein 1; AltName: Full=Protein p15;
FUNCTION: 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.
SUBUNIT: Heterodimer with NXF1. Interacts (via NTF2 domain) with NXF1. Stablizes the NTF2 domain of NXF1 by heterodimerization. The formation of NXF1/NXT1 heterodimers is required for the NXF1- mediated nuclear mRNA export. Preferentially binds Ran-GTP. Associates with NXF2, NXF3 and NXF5. Does not bind nucleoporins (NPC) directly, its association to NPC is mediated by NXF1.
INTERACTION: Q9UBU9:NXF1; NbExp=2; IntAct=EBI-301889, EBI-398874; Q9H4D5:NXF3; NbExp=3; IntAct=EBI-301889, EBI-750038; Q9BP41:Ranbp21 (xeno); NbExp=2; IntAct=EBI-301889, EBI-301896;
SUBCELLULAR LOCATION: Nucleus. Cytoplasm. Note=Shuttles between the nucleus and the cytoplasm.
SIMILARITY: Contains 1 NTF2 domain.

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

ModBase Predicted Comparative 3D Structure on Q9UKK6
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
