Members of this family are nucleolar RNA-associated proteins (Nrap) which are highly conserved from yeast (Saccharomyces cerevisiae) to human. In the mouse, Nrap is ubiquitously expressed and is specifically localised in the nucleolus [1]. Nrap is a large nucleolar protein (of more than 1000 amino acids).
