UTP18 Proteins and Enzymes

UTP18/WDR50 is a component of the small-subunit (SSU) processome, a large ribonucleoprotein complex that participates in ribosomal RNA processing and ribosome assembly. UTP18/WDR50 is a member of the WD repeat family. The WD repeat is defined by four or more repeating units of a conserved core of approximately 40 amino acids ending with tryptophan-aspartic acid (WD). WD repeats may serve as sites of protein-protein interaction for adaptor proteins and facilitate multiprotein complex formation.
