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, which may in turn recruit membrane vesicles containing pom121 and tmem48/ndc1. Association with chromatin may require the presence of the mcm2-mcm7 complex, suggesting a mechanism for coordination of nuclear assembly and the inactivation of replication licensing. Interacts with the Nup107-160 subcomplex of the NPC. Binds to chromatin during mitosis, and chromatin binding increases as nuclei assemble and grows through interphase (PubMed:17235358). Does not localize to the pores of annulate lamellae, which are cytoplasmic stacks of membrane that form in rapidly dividing cells (PubMed:18596237). 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.
