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 inner membrane of the nucleus is the membrane which separates the nuclear matrix from the intermembrane space. In mammals, the inner nuclear membrane is associated with heterochromatin and the nuclear lamina.
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.
Inner nuclear membrane protein (PubMed:2186029, PubMed:9199347, PubMed:18410727, PubMed:22751930). Involved in the attachment of membrane vesicles to chromatin during nuclear assembly, and is probably required for centrosome maturation and cell cycle progression during mitosis (PubMed:9199347, PubMed:22751930). Essential for differentiation of certain tissues and the maintenance of progenitor cell populations (PubMed:18410727, PubMed:24700158, PubMed:23806619, PubMed:27174470). Required for the differentiation and maintenance of male and female germline stem cells (GSCs), as well as the maintenance of somatic cells in the GSC niche (PubMed:18410727, PubMed:23806619, PubMed:27174470). This role is likely to be independent of the BMP (Dpp) pathway that negatively regulates bam transcription during GSC differentiation (PubMed:18410727, PubMed:23806619). During development, plays essential and redundant functions with the other LEM domain proteins; bocks and MAN1 (PubMed:24700158). Also has a redundant but important role with bocks during larval development (PubMed:24700158). {Experimental EvidencePubMed:18410727, Experimental EvidencePubMed:2186029, Experimental EvidencePubMed:22751930, Experimental EvidencePubMed:23806619, Experimental EvidencePubMed:24700158, Experimental EvidencePubMed:27174470, Experimental EvidencePubMed:9199347}.
