Ntf2 mediates nuclear import of ran
Web8 dec. 2024 · Binding of Ran to NTF2 is required for NTF2 to inhibit nuclear expansion and import of large cargo molecules. Nucleocytoplasmic translocation of NTF2 is regulated in mammalian cells. Data suggest actin accumulation in senescent cells is due to the failure of RanGTP restoration with ATP deficiency and NTF2 accumulation, resulting in decreased … WebRan is a small G protein that is essential for the translocation of RNA and proteins through the nuclear pore complex. The Ran protein has also been implicated in the control of DNA synthesis and cell cycle progression, as mutations in Ran have been found to disrupt DNA synthesis.

WebIsothermal titration calorimetry revealed that NTF2 prevents sumoylation by reducing RanGDP's affinity to RanBP2's RBDs to undetectable levels. Taken together, our findings indicate that RanGDP and not RanGTP is the physiological target for the RanBP2 SUMO E3 ligase complex.

Weband probably also mediates translocation of the NTF2– RanGDP complex to the nuclear side of the NPCs. A direct NTF2–RanGDP interaction is crucial for this process, since point mutations that disturb the RanGDP–NTF2 interaction also interfere with Ran import. The subsequent nuclear accumulation of Ran also requires GTP, but not GTP ...
Webthe docking of NLS-proteins at the nuclear pore complex (NPC). RanT24N, in contrast to wild-type Ran-GDP, interacts only weakly with importin α and nucleoporins, and not at all with the import factor p10, consistent with its poor activity in nuclear import. However, RanT24N does interact stably with importin β, Ran binding protein 1 and RCC1 ... grant county wv schoolsWeb17 jun. 2009 · RAN (Ras-related nuclear protein) is a small GTP-binding protein belonging to the RAS superfamily (see 190020) that is essential for the translocation of RNA and proteins through the nuclear pore complex ( Ren et al., 1993 ).

The rate of nuclear accumulation of FL-Ran(T24N) was <4% that of wild-type FL-Ran (Fig. 1B) and was similar to the rate of diffusion of green fluorescent protein (GFP) into the nucleus (15,16). chip and dale rescue rangers end creditsWebNTF2 binds RanGDP initially to NPCs and probably also mediates translocation of the NTF2–RanGDP complex to the nuclear side of the NPCs.
