Utp13 is a component of the five protein Pwp2 complex that forms part of a stable particle subunit independent of the U3 small nucleolar ribonucleoprotein that is essential for the initial assembly steps of the 90S pre-ribosome [1]. Pwp2 is capable of interacting directly with the 35 S pre-rRNA 5' end [1].	Domain
