Required for the assembly of a functional nuclear pore complex (NPC) on the surface of chromosomes as nuclei form at the end of mitosis. May initiate NPC assembly by binding to chromatin and recruiting the Nup107-160 subcomplex of the NPC. Also required for the localization of the Nup107-160 subcomplex of the NPC to the kinetochore during mitosis and for the completion of cytokinesis. Associates with the Nup107-160 subcomplex of the NPC. Localizes to the nuclear pore complex (NPC) throughout interphase. Localizes to the kinetochore from prophase, and this appears to require the Nup107-160 subcomplex of the NPC. Localizes to the periphery of chromatin from late anaphase. The N-terminus forms a highly conserved seven-bladed beta propeller decorated with long loops and mediates anchorage to the Nup107-160 subcomplex of the nuclear pore, synergistically with the central alpha domain. The disordered C-terminus is responsible for the interactions with chromatin (By similarity). Belongs to the ELYS family. Truncated N-terminus. Truncated N-terminus.
