Function
|
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. {ECO:0000269|PubMed:10523319, ECO:0000269|PubMed:10610322, ECO:0000269|PubMed:10684247, ECO:0000269|PubMed:11336711, ECO:0000269|PubMed:15208322}.

Subunit
|
The nuclear pore complex (NPC) constitutes the exclusive means of nucleocytoplasmic transport. NPCs allow the passive diffusion of ions and small molecules and the active, nuclear transport receptor-mediated bidirectional transport of macromolecules such as proteins, RNAs, ribonucleoparticles (RNPs), and ribosomal subunits across the nuclear envelope. The 55-60 MDa NPC is composed of at least 31 different subunits: ASM4, CDC31, GLE1, GLE2, NDC1, NIC96, NSP1, NUP1, NUP2, NUP100, NUP116, NUP120, NUP133, NUP145, NUP157, NUP159, NUP170, NUP188, NUP192, NUP42, NUP49, NUP53, NUP57, NUP60, NUP82, NUP84, NUP85, POM152, POM34, SEH1 and SEC1. Due to its 8-fold rotational symmetry, all subunits are present with 8 copies or multiples thereof. GLE1 interacts with the NUP82 subcomplex (NSP1, NUP82, NUP159) via NUP42. It also interacts with GFD1 and the ATP-dependent RNA helicase DBP5
