This domain is found at the N-terminal end of a group of archaeal proteins, including Uncharacterized NOP5 family protein MJ0694 from Methanocaldococcus jannaschii. This domain interacts with fibrillarin, the other subunit of a complex that is critical to modify and process ribosomal RNAs [1-5]. This domain shows a highly conserved folded structure despite low sequence similarity among homologs. It shows four beta-sheets surrounded by four alpha- helices [6] and is found associated with Pfam:PF01798.	Domain
