General Information
Term nuclear envelope ID (Ontology) GO:0005635 (Gene Ontology)
Definition The double lipid bilayer that encloses the nucleus, separating its contents from the cytoplasm. It consists of an inner and outer nuclear membrane, with an intermembrane space (20-40 nm wide, also called the perinuclear space) between them. The envelope is supported by the nuclear lamina and contains nuclear pore complexes, which regulate molecular transport.[ ISBN:0198547684 PubMed:16164970 ]
