A double membrane structure enclosing an organelle, including two lipid bilayers and the region between them. In some cases, an organelle envelope may have more than two membranes. A protein complex that forms part of the nuclear pore complex, and is required for its correct assembly. In Saccharomyces cerevisiae Nic96 contains Nsp1p, Nup57p, Nup49p, and Nic96p. A protein complex that forms part of the nuclear pore complex. It forms a subcomplex with Nup159p and Nsp1p, interacts with Nup116p, and is required for proper localization of Nup116p. In Saccharomyces cerevisiae this complex contains Nup82p, Nsp1p, Nup159p, Nup116p, and Gle2p. A protein complex that forms part of the nuclear pore complex, and contains three transmembrane nucleoporins, encoded in S. cerevisiae by Ndc1p, Pom152p and Pom34p. A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. The double lipid bilayer enclosing the nucleus and separating its contents from the rest of the cytoplasm; includes the intermembrane space, a gap of width 20-40 nm (also called the perinuclear space). A collection of membranous structures involved in transport within the cell. The main components of the endomembrane system are endoplasmic reticulum, Golgi bodies, vesicles, cell membrane and nuclear envelope. Members of the endomembrane system pass materials through each other or though the use of vesicles. Any small opening in a membrane that allows the passage of gases and/or liquids. Any macromolecular complex composed of two or more polypeptide subunits, which may or may not be identical. Protein complexes may have other associated non-protein prosthetic groups, such as nucleotides, metal ions or other small molecules. Any of the numerous similar discrete openings in the nuclear envelope of a eukaryotic cell, where the inner and outer nuclear membranes are joined. A subcomplex of the nuclear pore complex that interacts with karyopherin-cargo complexes; a well-characterized example in Saccharomyces contains Asm4p, Nup53p, and Nup170p. Any constituent part of the nucleus, a membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. A subcomplex of the nuclear pore complex (NPC) involved in mRNA export and NPC assembly. Contains conserved nucleoporins and other proteins; for example, the Saccharomyces complex contains Nup84p, Nup85p, Nup120p, Nup145p-C, Seh1p, Sec13p, and Nup133p. A constituent part of an intracellular organelle, an organized structure of distinctive morphology and function, occurring within the cell. Includes constituent parts of the nucleus, mitochondria, plastids, vacuoles, vesicles, ribosomes and the cytoskeleton but excludes the plasma membrane. Penetrating at least one phospholipid bilayer of a membrane. May also refer to the state of being buried in the bilayer with no exposure outside the bilayer. When used to describe a protein, indicates that all or part of the peptide sequence is embedded in the membrane.
