ELYS (embryonic large molecule derived from yolk sac) is conserved from fungi such Aspergillus nidulans and Schizosaccharomyces pombe to human [1]. It is important for the assembly of the nuclear pore complex [2].

1: MEL-28/ELYS is required for the recruitment of nucleoporins to chromatin and postmitotic nuclear pore complex assembly. Franz C, Walczak R, Yavuz S, Santarella R, Gentzel M, Askjaer P, Galy V, Hetzer M, Mattaj IW, Antonin W; EMBO Rep. 2007;8:165-172. PMID:17235358

2: The three fungal transmembrane nuclear pore complex proteins of Aspergillus nidulans are dispensable in the presence of an intact An-Nup84-120 complex. Liu HL, De Souza CP, Osmani AH, Osmani SA; Mol Biol Cell. 2009;20:616-630. PMID:19019988
