The N-terminal domain of NUP93, the eponymous subunit of the Nup93 complex, recruits the Nup62 complex, consisting of phenylglycine (FG) repeat-containing nucleoporins NUP62, NUP58 and NUP54 (Chug et al. 2015), to the nascent nuclear pore complex (NPC) (Sachdev et al. 2012). The barrier function of the NPC is reestablished at this point (Dultz et al. 2008).
