Nucleoporin 205
Nucleoporin 205 (Nup205) is a protein that in humans is encoded by the NUP205 gene. Function 
Transport of macromolecules between the cytoplasm and nucleus occurs through nuclear pore complexes (NPCs) embedded in the nuclear envelope. NPC's are composed of subcomplexes, and NUP205 is part of one such subcomplex. It has also been recently shown that Nup205 is required  for proper viral gene expression. References
