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). Web相关研究结果发表在2024年12月10日的Science期刊上，论文标题为“ Nuclear pores dilate and constrict in cellulo ”。 这些作者概述了对一种概念模型的几个预测，在这种概念模型中，核膜张力调节NPC直径。 在这种情况下，核体积和NPC直径应该是相互依赖的。 NPC支架的刚性应当会抵消它的扩张。 在膜弹性理论的基础上，他们预测核膜腔内的渗透压和核 …

They are ancient assemblies that were likely present in the last eukaryotic common ancestor and, as such, are made up of a conserved set of ∼30 proteins termed nucleoporins or “nups.” cost of parking at moncton airport
