Coupling of the nucleus and cytoplasm
The nuclear envelope defines the barrier between the nucleus and cytoplasm and features inner and outer membranes separated by a perinuclear space (PNS). The inner nuclear membrane contains specific integral proteins that include Sun1 and Sun2. Although the outer nuclear membrane (ONM) is continuous with the endoplasmic reticulum, it is nevertheless enriched in several integral membrane protein...
متن کاملTransport of macromolecules between the nucleus and the cytoplasm.
Nuclear transport is an energy-dependent process mediated by saturable receptors. Import and export receptors are thought to recognize and bind to nuclear localization signals or nuclear export signals, respectively, in the transported molecules. The receptor-substrate interaction can be direct or mediated by an additional adapter protein. The transport receptors dock their cargoes to the nucle...
متن کاملTransport pathways of macromolecules between the nucleus and the cytoplasm.
Transport between the nucleus and cytoplasm involves both stationary components and mobile factors acting in concert to move macromolecules through the nuclear pore complex. Multiple transport pathways requiring both unique and shared components have been identified. In the past 18 months, new findings have shed light on the nature of some of the mobile components of these pathways. New recepto...
متن کاملShuttling of galectin-3 between the nucleus and cytoplasm.
In previous studies, we documented that galectin-3 (M(r) approximately 30,000) is a pre-mRNA splicing factor. Recently, galectin-3 was identified as a component of a nuclear and cytoplasmic complex, the survival of motor neuron complex, through its interaction with Gemin4. To test the possibility that galectin-3 may shuttle between the nucleus and the cytoplasm, human fibroblasts (LG-1) were fu...
متن کاملDynamics of galectin-3 in the nucleus and cytoplasm.
This review summarizes selected studies on galectin-3 (Gal3) as an example of the dynamic behavior of a carbohydrate-binding protein in the cytoplasm and nucleus of cells. Within the 15-member galectin family of proteins, Gal3 (M(r) approximately 30,000) is the sole representative of the chimera subclass in which a proline- and glycine-rich NH(2)-terminal domain is fused onto a COOH-terminal ca...
