The founding member of this family is the pre-PUA domain of the Pyrococcus abyssi Nip7 (PaNip7). This domain folds into a five-stranded antiparallel beta-sheet surrounded by three alpha-helices [1]. It is anticipated that this domain interacts with proteins involved in pre-rRNA processing, such as Rrp43p, Nop8p or Nop53p.
