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.
