NTF2-related export protein 1 is a protein that in humans is encoded by the NXT1 gene.{{cite journal |vauthors=Black BE, Levesque L, Holaska JM, Wood TC, Paschal BM | title = Identification of an NTF2-related factor that binds Ran-GTP and regulates nuclear protein export | journal = Mol Cell Biol | volume = 19 | issue = 12 | pages = 8616–24 |date=Jan 2000 | pmid = 10567585 | pmc = 84993 | doi = 10.1128/MCB.19.12.8616}}{{cite journal |vauthors=Guzik BW, Levesque L, Prasad S, Bor YC, Black BE, Paschal BM, Rekosh D, Hammarskjold ML | title = NXT1 (p15) is a crucial cellular cofactor in TAP-dependent export of intron-containing RNA in mammalian cells | journal = Mol Cell Biol | volume = 21 | issue = 7 | pages = 2545–54 |date=Mar 2001 | pmid = 11259602 | pmc = 86886 | doi = 10.1128/MCB.21.7.2545-2554.2001 }}{{cite web | title = Entrez Gene: NXT1 NTF2-like export factor 1| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=29107| accessdate = }}

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 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.
