The single transmembrane segment (TM) of gp210 is sufficient for sorting to the pore membrane domain of the nuclear envelope, as demonstrated by expression of wild-type, mutant, and chimeric gp210 constructs in 3T3 cells; the cytoplasmic tail (CT) also contains a weaker sorting determinant. The large cisternal domain (95% of gp210's mass) contains no sorting determinants. |

Gp210 is specifically phosphorylated during mitosis (not in interphase) at Ser1880 in its cytoplasmic tail, consistent with phosphorylation by cyclin B-p34cdc2 or a related kinase, as determined by cell cycle-specific phosphorylation assays and in vitro phosphorylation mapping of mutant fusion proteins containing the cytoplasmic domain. |

Gp210 forms SDS-resistant dimers and larger oligomers in the nuclear pore membrane, as shown by immunoprecipitation from cell extracts and velocity sedimentation/gel filtration from purified rat liver nuclear envelopes; cross-linking prior to solubilization dramatically increased the proportion of dimers. |

The cytoplasmic tail of gp210 is required for nuclear pore dilation and NPC assembly: adding recombinant tail polypeptides or anti-tail antibodies to Xenopus nuclear assembly extracts blocked NPC assembly and nuclear growth without affecting membrane fusion, and inhibited nuclei failed to incorporate Nup214/CAN, Nup153, and Nup98. EM revealed arrested 'mini-pore' structures and a lack of 'closely apposed' inner and outer nuclear membranes. |

The C-terminal domain (CTD) of human gp210 adopts a largely unordered conformation with significant polyproline type II (PII) helical structure in solution; the conformation is altered by high pH, charged detergents, and TFE, and TFE induces a conformational change around the SPXX motif containing Ser1880 (the mitotically phosphorylated serine). |

RNAi-mediated depletion of gp210 in HeLa cells is lethal and causes accumulation of clustered NPCs and aberrant nuclear membrane structures, indicating gp210 is required for nuclear pore formation/dilation and structural integrity of NPCs. In C. elegans, gp210 RNAi causes embryonic lethality with similar nuclear membrane aberrations, demonstrating evolutionary conservation of function. |

In NIH/3T3 cells lacking gp210, POM121 and NUP107 are correctly distributed at nuclear pores and remain stably associated as assessed by FRAP, indicating that gp210 is not required for incorporation of POM121 or NUP107 or for maintaining NPC stability. |

POM121 can recruit nucleoporins (Nup62, Nup358) to ectopic assembly sites and acts as a nucleation site for NPC substructures. Double knockdown of gp210 and POM121 in HeLa cells, and depletion of POM121 in human fibroblasts (which do not express gp210), still permits functional NPC assembly, indicating extensive redundancy and that additional membrane-integral nucleoporins exist for NE anchorage. |

Phosphomimetic substitution S1880E of gp210 specifically interferes with incorporation of gp210 into NPCs and compromises its post-mitotic recruitment to daughter nuclei, while the alanine substitution S1880A makes gp210 more dynamic at the NPC (faster FRAP), suggesting that mitotic phosphorylation at Ser1880 acts to dissociate gp210 from the NPC. |

Gp210 is required for nuclear envelope breakdown (NEBD) in mitosis: RNAi depletion or mutation of C. elegans gp210 prevents lamin depolymerization and causes nuclear twinning after mitosis. Anti-gp210 C-terminal tail antibodies added to in vitro assembled nuclei completely blocked NEBD and inhibited mitotic hyperphosphorylation of gp210. Depletion of cyclin B from C. elegans embryos also causes nuclear twinning, consistent with cyclin B-cdc2 being the relevant kinase. |

Super-resolution dSTORM imaging of isolated Xenopus laevis oocyte nuclear envelopes demonstrates that gp210 is distributed with eightfold radial symmetry around the NPC, placing it at each of the eight subunits of the NPC ring; the central NPC channel diameter was determined to be 41 ± 7 nm. |

Gp210/Nup210 mediates muscle cell differentiation via its conserved N-terminal luminal domain; the C-terminal domain (which targets gp210 to NPCs) is dispensable and a mutant lacking both the transmembrane and C-terminal domains is sufficient for C2C12 myoblast differentiation. ER stress-specific caspase cascade is exacerbated during Nup210 depletion, and blocking ER stress-mediated apoptosis rescues differentiation of Nup210-deficient cells, indicating the luminal domain maintains nuclear envelope/ER homeostasis. |

Nup210 is required during chemical reprogramming of mouse fibroblasts into neural stem cells (NSCs): Nup210 activates SoxB1 transcription factors to initiate NSC fate, and its activity is required for both chemical cocktail- and growth factor (IL-6, FGF5, LIF)-driven reprogramming. |

NUP210 interacts with LINC complex protein SUN2 (connecting nucleus to cytoskeleton), and the NUP210/SUN2 complex further interacts with chromatin via the short isoform of BRD4 and histone H3.1/H3.2 at the nuclear periphery. Nup210 depletion causes accumulation of H3K27me3 heterochromatin (mediated by PRC2) at mechanosensitive genes, repositioning of these genes within the nucleus, and defective mechanotransduction and focal adhesion. |

A FRET-based tension biosensor inserted into gp210 (at endogenous levels via CRISPR knock-in) reveals that gp210 and the NPC experience mechanical tension. Forces on gp210 increase with osmotically induced nuclear swelling and are influenced by ECM stiffness, the LINC complex, chromatin condensation, and actomyosin contractility; chromatin relaxation and MLCK inhibition increase gp210 forces, suggesting nuclear strain (rather than cytoskeletal forces) is the predominant source of NPC forces. |

Nup210 knockdown promotes HIV-1 infection by increasing accumulation of integrated proviral DNA, while levels of reverse transcription products and 2-LTR circles (nuclear entry intermediates) are unaffected, indicating Nup210 acts at late steps of viral nuclear entry (post-nuclear entry, affecting integration). Nup210 also regulates viral mRNA alternative splicing; knockdown increases singly spliced Vpr mRNA, and elevated Vpr may act as a viral antagonist of Nup210. |
