WebIn this work just out in Science we show two physiological cues that allow nuclear pores to dilate and constrict in living cells revealing a mechanism regulated by membrane tension. Web1 jul. 2024 · Nuclear pore complexes (NPCs) regulate all molecular transport between the nucleus and the cytoplasm in eukaryotic cells. Intrinsically disordered Phe-Gly nucleoporins (FG-Nups) line the central conduit of NPCs to impart a selective barrier where large proteins are excluded unless bound to a transport receptor (karyopherin; Kap).
http://www.bioon.com.cn/protocol/showarticle.asp?newsid=92728 WebIn eukaryotic cells, nuclear pore complexes (NPCs) fuse the inner and outer nuclear membranes and mediate nucleocytoplasmic exchange. They are made of 30 different nucleoporins and form a cylindrical architecture around an aqueous central channel. This architecture is highly dynamic in space and time.
