21. He has also proposed an analytical model to elucidate the mechanism of protein transport across the nuclear pore complex. 22. This is because it interacts with both RNA-binding adapter proteins and components of the nuclear pore complex. 23. Small particles ( < ~ 40 kDa ) are able to pass through the nuclear pore complex by passive diffusion. 24. In budding yeast, the Ulp1 SUMO protease is found bound at the nuclear pore , whereas Ulp2 is nucleoplasmic. 25. FG-nucleoporins also contain a globular portion that serves as an anchor for attachment to the nuclear pore complex. 26. Small ubiqutin-related modifier needs to be associated with it before it can be localized at the nuclear pore . 27. She discusses how nuclear pore complexes ( NPCs ) are the location for the entrance and exit of the nucleus. 28. Ran is a small G protein that is essential for the translocation of RNA and proteins through the nuclear pore complex. 29. Nucleoporins, a family of around 30 proteins, are the main components of the nuclear pore complex in eukaryotic cells. 30. The protein is localized to the nuclear rim and is an essential component of the nuclear pore complex ( NPC ).
