This domain is found in Nucleoporin NUP120 from Saccharomyces cerevisiae and similar fungal sequences. NUP120 is a a component of the nuclear pore complex (NPC) involved in nuclear poly(A)+ RNA and pre-ribosome export, in GSP1 nuclear import, in NPC assembly and distribution, as well as in nuclear envelope organisation. This entry represents the alpha-helical domain of NUP120, which packs against the side of the beta-propeller Pfam:PF11715, located N-terminal of the protein [1-4].	Domain
