Summaries for NXT1 Gene

Entrez Gene Summary for NXT1 Gene

  • 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]

GeneCards Summary for NXT1 Gene

    Quaternary structure:
    • 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.
