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.
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.
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 bidirectional transport of macromolecules such as proteins, RNAs etc across the double-membrane nuclear envelope.The NPC is composed of at least 30 distinct subunits known as Nucleoporins (NUPs).
Part of the nuclear pore complex (NPC) (PubMed:25197089). Required for MAD import as part of the Nup107-160 complex and required for nuclear export of Moe probably via its association with Rae1 (PubMed:20547758, PubMed:28554770). Plays a role in nuclear mRNA export (PubMed:28554770). Promotes cell antiviral response by up-regulating FoxK-dependent antiviral gene transcription (PubMed:25197089, PubMed:25852164). In germline stem cells, involved in their maintenance and division together with the TGF-Beta and EGFR signaling pathways (PubMed:21949861). In larval lymph glands, has a role in the maintenance of hematopoiesis by regulating Pvr expression (PubMed:25201876). {Experimental EvidencePubMed:20547758, Experimental EvidencePubMed:21949861, Experimental EvidencePubMed:25197089, Experimental EvidencePubMed:25201876, Experimental EvidencePubMed:25852164, Experimental EvidencePubMed:28554770}. [Nuclear pore complex protein Nup98]: Part of the nuclear pore complex (NPC) (PubMed:25310983). In the nucleoplasm, binds to transcriptionally active chromatin with a preference for regulatory regions; co-localizes with RNA polymerase II in a RNA-independent manner and before transition into transcription elongation (PubMed:20144760, PubMed:20144761, PubMed:28366641). Plays a role in the transcriptional memory process by stabilizing enhancer-promoter loops and by mediating anchoring of chromatin to the nuclear pore complex region (PubMed:28366641). During larval development, interacts with trx and MBD-R2 and regulates transcription of developmental genes including ecdysone-responsive genes such as Eip74 and E23 (PubMed:20144761, PubMed:25310983, PubMed:28366641). {Experimental EvidencePubMed:20144760, Experimental EvidencePubMed:20144761, Experimental EvidencePubMed:25310983, Experimental EvidencePubMed:28366641}.
