This entry represents the N-terminal domain of archaeal Nop5, a Nop56/58 homologue which are pre-RNA processing ribonucleoproteins (RNP). This domain is very well conserved and mediates a stable interaction with fibrillarin, playing a role in both RNP assembly and methyltransferase activity [1].	Domain
