Graphical View of Domain Structure for InterPro Entry



  • Q9GZY0
  • The NTF2 domain heterodimerizes with NXT1 and NXT2. The formation of NXF1/NXT1 heterodimers is required for NXF2-mediated nuclear mRNA export
  • The leucine-rich repeats and the NTF2-domain are essential for the export of mRNA from the nucleus
  • The C-terminal fragment, containing the TAP domain (also called UBA-like domain) and part of the NTF2-like domain, named the NPC-binding domain, mediates direct interactions with nucleoporin-FG-repeats and is necessary and sufficient for localization of NXF2 to the nuclear rim
  • The RNA-binding domain is a non-canonical RNP-type domain
  • Contains 1 NTF2 domain.
  • Contains 1 RRM (RNA recognition motif) domain.
  • Contains 1 TAP-C domain.
  • Belongs to the NXF family.
  • Contains 4 LRR (leucine-rich) repeats.
