    ..We experimentally confirmed the sufficiency of diffusion and retention using an artificial reporter lacking natural sorting signals that recapitulates the energy dependence of the process in vivo. ..
  2. Ungricht R, Kutay U. Establishment of NE asymmetry—targeting of membrane proteins to the inner nuclear membrane. Curr Opin Cell Biol. 2015;34:135-41 pubmed publisher
    ..These studies reveal that nuclear retention, diffusional mobility in the ER as well as the number and architecture of NPCs are major determinants of INM targeting, collectively lending support to a diffusion-retention-based mechanism. ..

    ..Overexpression of BCCIPβ leads to nucleoplasmic accumulation of extra-ribosomal RPL23 and stabilizes overexpressed RPL23, suggesting that BCCIPβ functions as nuclear chaperone for RPL23. ..
