Gene ontology ID
GO:0034388
Definition
A protein complex that forms a subcomplex of the 90S preribosome and can interact directly with the 5' External Transcribed Spacer (ETS) of the full length pre-rRNA transcript. In S. cerevisiae, it sediments at 25-30 S and is composed of Pwp2p, Dip2p, Utp21p, Utp13p, Utp18p, and Utp6p
Comment
Note that the term name uses Saccharomyces gene product names because no other names have yet arisen for this complex; the term nevertheless can be used for analogous complexes in other eukaryotes, and the name can be changed if better wording is found.
Synonyms
1. 25-30 S subcomplex of 90S preribosome
2. UTP-B complex
