| Location | Location ID | Description |
| Nuclear Envelope | SL-0178 | The nuclear envelope is a membrane system which surrounds the nucleoplasm of eukaryotic cells. It is composed of the nuclear lamina, nuclear pore complexes and two nuclear membranes. The space between the two membranes is called the nuclear intermembrane space. |
| Nuclear Membrane | SL-0182 | The membrane surrounding the nucleus. This term is used when it is not known if the protein is found in or associated with the inner or outer nuclear membrane. | Membrane Topology |

Description |

|---|---|
| Required for the export of nuclear mRNAs and involved in mRNA trafficking in the cytoplasm (PubMed:27016737, PubMed:28554770, PubMed:33602059). Component of the nuclear pore complex (NPC)- associated TREX-2/AMEX complex (anchoring and mRNA export complex) which functions in docking export-competent ribonucleoprotein particles (mRNPs) to the nuclear entrance of the nuclear pore complex (nuclear basket), thereby enabling the export of mRNAs to the cytoplasm through the nuclear pores (PubMed:27016737, PubMed:28554770, PubMed:33602059). Within the complex, specifically promotes the association of factors involved in regulating nuclear mRNA export, such as Moe, sbr/NXF1 and the ORC complex, to the mRNPs particles (PubMed:27016737, PubMed:28554770, PubMed:33602059). In the cytoplasm, functions independently of its role in the TREX-2/AMEX complex, to promote cytoplasmic mRNA trafficking together with nudC (PubMed:33602059). Associates with translationally active polysomes (PubMed:18086857). {Experimental EvidencePubMed:18086857, Experimental EvidencePubMed:27016737, Experimental EvidencePubMed:28554770, Experimental EvidencePubMed:33602059}. | Assigned Ontology terms |
