U3 snoRNA associated (IPR013268)

Short name: U3_snoRNA_assoc

Overlapping homologous superfamilies


Family relationships



This family of proteins is associated with U3 snoRNA [PMID: 12068309]. U3 snoRNA is required for nucleolar processing of pre-18S ribosomal RNA. Proteins in this family include Bud21 from S. cerevisiae. Bud21 is a component of small ribosomal subunit (SSU) processosome and has a role in bud site selection maybe via the regulation of expression of bipolar budding components [PMID: 12068309, PMID: 11452010].
