Introduction

Pfam

This family consists of various Pre RNA processing ribonucleoproteins. The function of the aligned region is unknown however it may be a common RNA or snoRNA or Nop1p binding domain. Nop5p (Nop58p) Q12499 from yeast is the protein component of a ribonucleoprotein required for pre-18s rRNA processing and is suggested to function with Nop1p in a snoRNA complex [1]. Nop56p O00567 and Nop5p interact with Nop1p and are required for ribosome biogenesis [2]. Prp31p p49704 is required for pre-mRNA splicing in S. cerevisiae [3]. Fibrillarin, or Nop, is the catalytic subunit responsible for the methyl transfer reaction of the site-specific 2'-O-methylation of ribosomal and spliceosomal RNA [4].

The Nop domain is present in various pre-RNA processing ribonucleoproteins (RNP):
