Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0002041
UniProt IDQ9UKK6
Primary gene name(s)NXT1
Synonym gene name(s)unknown
Protein nameNTF2-related export protein 1
Protein functionStimulator 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. {ECO:0000269|PubMed:10567585, ECO:0000269|PubMed:10848583, ECO:0000269|PubMed:11259602, ECO:0000269|PubMed:19165146}.
Subcellular locationNucleus. Nucleus speckle {ECO:0000305}. Cytoplasm. Note=Shuttles between the nucleus and the cytoplasm.
