== Function == | |||
[[http://www.uniprot.org/uniprot/GLE1_YEAST GLE1_YEAST]] Functions as a component of the nuclear pore complex (NPC). NPC components, collectively referred to as nucleoporins (NUPs), can play the role of both NPC structural components and of docking or interaction partners for transiently associated nuclear transport factors. It is specifically involved in a terminal step of poly(A)+ mRNA transport through the NPC probably by binding the ATP-dependent RNA helicase DBP5 and GFD1 at the cytoplasmic side of the NPC. These interactions are thought to be important for the dissociation of transport proteins such as the heterogeneous nuclear ribonuleoprotein (hnRNP) NAB2 from exported mRNA.<ref>PMID:10523319</ref> <ref>PMID:10610322</ref> <ref>PMID:10684247</ref> <ref>PMID:11336711</ref> <ref>PMID:15208322</ref> [[http://www.uniprot.org/uniprot/NUP42_YEAST NUP42_YEAST]] Functions as a component of the nuclear pore complex (NPC). NPC components, collectively referred to as nucleoporins (NUPs), can play the role of both NPC structural components and of docking or interaction partners for transiently associated nuclear transport factors. Active directional transport is assured by both, a Phe-Gly (FG) repeat affinity gradient for these transport factors across the NPC and a transport cofactor concentration gradient across the nuclear envelope (GSP1 and GSP2 GTPases associated predominantly with GTP in the nucleus, with GDP in the cytoplasm). NUP42 is specifically important for nuclear protein and mRNA export.<ref>PMID:10523319</ref> <ref>PMID:10610322</ref> <ref>PMID:10805742</ref> <ref>PMID:10952996</ref> <ref>PMID:11387327</ref> <ref>PMID:12604785</ref> <ref>PMID:12917401</ref> <ref>PMID:15039779</ref> | |||
