CAN/Nup214 forms a dynamic subcomplex at the nuclear pore complex with Nup88 and human CRM1 (hCRM1). Depletion of CAN from the NPC causes concomitant loss of Nup88, indicating Nup88 NPC localization depends on CAN binding. The FG-repeat region of CAN contains the hCRM1-interaction domain; nuclear overexpression of this region depletes hCRM1 from the NPC. |

CAN/Nup214 is essential for cell cycle progression and nucleocytoplasmic transport in vivo. CAN-/- mouse embryos arrest in G2 phase upon depletion of maternally derived CAN, accompanied by inhibition of NLS-mediated nuclear protein import and nuclear accumulation of poly(A)+ RNA (mRNA export block). CAN-/- ES cells are not viable. |

DBP5/DDX19 binds NUP214 in a manner mutually exclusive with RNA binding. Crystal structures of human DBP5 bound to RNA/AMPPNP and to NUP214 show overlapping binding surfaces. NUP214 decreases both RNA-binding and ATPase activities of DBP5 in vitro, suggesting NUP214 acts as a negative regulator that resets DBP5 at the cytoplasmic face of the NPC for mRNA release. |

Crystal structure of a 117-amino-acid FG-repeat fragment of Nup214 in complex with CRM1, Snurportin1, and RanGTP at 2.85 Å resolution reveals eight binding sites for Nup214 FG motifs on CRM1. Nup214 binds to both N- and C-terminal regions of CRM1, clamping it in a closed conformation and stabilizing the export complex. Conserved hydrophobic pockets on CRM1 are required for FG-motif recognition, validated by biochemical and cell-based assays. |

Smad2 directly interacts with NUP214/CAN and Nup153 to mediate constitutive nucleocytoplasmic shuttling. CAN/Nup214 and Nup153 compete with the cytoplasmic retention factor SARA and the nuclear partner FAST-1 for binding to a hydrophobic corridor on the MH2 surface of Smad2.

Nup88 localizes between Nup358 and Nup214 at the cytoplasmic NPC face and physically interacts with both. RNAi depletion of either Nup88 or Nup214 causes strong reduction of Nup358 at the nuclear envelope, demonstrating that Nup88 and Nup214 mediate the attachment of Nup358 to the NPC. Nup88 and Nup214 are interdependent at the NPC and are not affected by absence of Nup358. |

Depletion of the Nup214-Nup88 nucleoporin subcomplex by RNAi causes a dramatic defect in CRM1-mediated nuclear export of the 60S preribosomal subunit (via NMD3 adaptor). The coiled-coil region of Nup214 (not the FG-repeat domain) is sufficient for rescuing 60S export, coinciding with recruitment of Nup88. The large FG domain of Nup214 is not accessible to freely diffusing nuclear molecules. |

CAN/Nup214 is a docking site for incoming adenovirus type 2 (Ad2) capsids at the NPC. Capsid binding to CAN is independent of cytosolic factors. Capsid disassembly at the NPC requires nuclear histone H1 binding to stably docked capsids, involving H1-import factors, thereby restricting irreversible DNA release to NPC proximity. |

Expression of an NPC-targeted N-terminal Nup214 domain in Nup214-depleted cells restores hexon binding and viral genome import. |

Overexpression of the C-terminal FG-repeat region alone sequesters hCRM1 in the nucleoplasm (and importin beta/p97 from the NPC), which is sufficient to inhibit cell growth and induce apoptosis, confirming that CAN's FG region interacts with hCRM1 and that this interaction is functionally critical. |

In Drosophila, Nup214 binds CRM1 directly and anchors it to the nuclear envelope. In nup214 mutants, CRM1 accumulates in the nucleus and NES-protein export is enhanced. The Nup214-Nup88 complex sequesters CRM1 at the nuclear rim; Nup214 protects Nup88 from degradation while Nup88 is sufficient for targeting the complex to nuclear pores. The NFκB transcription factor Dorsal is a CRM1 substrate requiring Nup214 for nuclear translocation upon signaling. |

Nup214 and its partner Nup88 negatively regulate Notch signaling in mammalian cells and in vivo in zebrafish. Loss of Nup88/214 inhibits nuclear export of RBP-J (the DNA-binding component of the Notch pathway), increasing RBP-J binding to cognate promoter regions and enhancing downstream Notch signaling. Nuclear RBP-J levels are rate-limiting for Notch signaling. |
