Exploring the LINC to nuclear envelope spacing
L INC complexes do not maintain the space between nuclear membranes, except in cells exposed to mechanical stress, Cain et al. reveal. SUN proteins in the inner nuclear membrane and KASH proteins in the outer nuclear membrane form LINC complexes that regulate multiple processes by connecting the nucleoskeleton to the cytoskeleton. LINC complexes are also thought to maintain a uniform gap of ~50...
متن کاملAn unresolved LINC in the nuclear envelope.
The nuclear envelope segregates the nucleoplasm from the cytoplasm and is a key feature of eukaryotic cells. Nuclear envelope architecture is comprised of two concentric membrane shells which fuse at multiple sites and yet maintain a uniform separation of 30-50 nm over the rest of the membrane. Studies have revealed the roles for numerous nuclear proteins in forming and maintaining the architec...
متن کاملNuclear envelopathies: a complex LINC between nuclear envelope and pathology
Since the identification of the first disease causing mutation in the gene coding for emerin, a transmembrane protein of the inner nuclear membrane, hundreds of mutations and variants have been found in genes encoding for nuclear envelope components. These proteins can be part of the inner nuclear membrane (INM), such as emerin or SUN proteins, outer nuclear membrane (ONM), such as Nesprins, or...
متن کاملSUN proteins and nuclear envelope spacing
The nuclear envelope consists of 2 membranes separated by 30-50 nm, but how the 2 membranes are evenly spaced has been an open question in the field. Nuclear envelope bridges composed of inner nuclear membrane SUN proteins and outer nuclear membrane KASH proteins have been proposed to set and regulate nuclear envelope spacing. We tested this hypothesis directly by examining nuclear envelope spa...
متن کاملOuter nuclear membrane protein Kuduk modulates the LINC complex and nuclear envelope architecture
Linker of nucleoskeleton and cytoskeleton (LINC) complexes spanning the nuclear envelope (NE) contribute to nucleocytoskeletal force transduction. A few NE proteins have been found to regulate the LINC complex. In this study, we identify one, Kuduk (Kud), which can reside at the outer nuclear membrane and is required for the development of Drosophila melanogaster ovarian follicles and NE morpho...
